[PATCH 1/3] MIPS: sgi-ip32: Clear latched CRIME errors at boot

[Imre Kaloz <kaloz@kernel.org>]

Errors already latched in CRIME when the kernel starts are reported as
new, as a "CRIME memory error" or a "CRIME CPU error", once the error
interrupts are enabled. Clear both status registers in crime_init().
