This adds in support for building with ARCH=sh64 using the sh SRCARCH. This tidies up the randconfig generation somewhat to make sure that we don't end up with impossible configurations, and without having to rely on things like KCONFIG_ALLCONFIG to detect the proper CPU support subset.

This corrects a race with the PHY RST bit not being set properly if the PLL status changes right before timeout. This resulted in it potentially failing even if the device came up in time.
