cpu_get_desc() for the RISC-V CPU currently reads "riscv,isa" to get
the description, but it is no longer a required property and cannot be
assummed to always be present, as the new "riscv,isa-extensions" and
"riscv,isa-base" properties may be present instead.
On RISC-V, cpu_get_desc() has two main uses - firstly providing an
informational name for the CPU for smbios or at boot with
DISPLAY_CPUINFO etc and secondly it forms the basis of ISA extension
detection in supports_extension() as it returns (a portion of) an ISA
string.
cpu_get_desc() returns a string, which aligned with "riscv,isa" but
the new property is a list of strings. Rather than add support for
the list of strings property, which would require creating an isa
string from "riscv,isa-extensions", modify the RISC-V CPU's
implementaion of cpu_get_desc() return the first compatible as the
cpu description instead. This may be fine for the informational cases,
but it would break extension dtection, given supports_extension()
expects cpu_get_desc() to return an ISA string.
Call dev_read_string() directly in supports_extension() to get the
contents of "riscv,isa" so that extension detection remains functional.
As a knock-on affect of this change, extension detection is no longer
broken for long ISA strings. Previously if the ISA string exceeded the
32 element array that supports_extension() passed to cpu_get_desc(),
it would return ENOSPC and no extensions would be detected.
This bug probably had no impact as U-Boot does not currently do anything
meaningful with the results of supports_extension() and most SoCs
supported by U-Boot don't have anywhere near that complex of an ISA
string. The QEMU virt machine's CPUs do however, so extension detection
doesn't work there.

The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.
With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

sandbox,timebase-frequency-fallback controls whether sandbox_timer_probe

The cmd "cpu detail" fetches uninitialized cpu feature information
and thus displays wrong / inconsitent details as below.
For eg: FU540-C000 doesn't have any microcode, yet the cmd display's it.
=> cpu detail
1: cpu@1 rv64imafdc
ID = 1, freq = 999.100 MHz: L1 cache, MMU, Microcode, Device ID
Microcode version 0x0
Device ID 0x0
2: cpu@2 rv64imafdc
ID = 2, freq = 999.100 MHz: L1 cache, MMU, Microcode, Device ID
Microcode version 0x0
Device ID 0x0
3: cpu@3 rv64imafdc
ID = 3, freq = 999.100 MHz: L1 cache, MMU, Microcode, Device ID
Microcode version 0x0
Device ID 0x0
4: cpu@4 rv64imafdc
ID = 4, freq = 999.100 MHz: L1 cache, MMU, Microcode, Device ID
Microcode version 0x0
Device ID 0x0
The L1 cache or MMU entry seen above is also displayed inconsistently.
So initialize cpu information to zero into cpu-uclass itself so that
similar issues can be avoided for other CPU drivers.
We now see correct features as:

ID = 1, freq = 999.100 MHz
2: cpu@2 rv64imafdc
