ARM: dts: ti: omap: Fix noisy serial with overrun-throttle-ms for mapphone
[ Upstream commit 5ad37b5e30433afa7a5513e3eb61f69fa0976785 ] On mapphone devices we may get lots of noise on the micro-USB port in debug uart mode until the phy-cpcap-usb driver probes. Let's limit the noise by using overrun-throttle-ms. Note that there is also a related separate issue where the charger cable connected may cause random sysrq requests until phy-cpcap-usb probes that still remains.
