mtd: rawnand: denali_dt: make the core clock optional
The "nand_x" and "ecc" clocks are currently optional. Make the core clock optional in the same way. This will allow platforms with no clock driver support to use this driver. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Tested-by: Marek Vasut <marex@denx.de> # On SoCFPGA Arria V
