The regulator MT6359P is needed by both firmware display and SD card.
To avoid duplicate initialization in ramstage, publicize init_pmif_arb()
as mt6359p_init_pmif_arb() and call it from mainboard_init(). This would
save 13 ms for boot time on Geralt.
BUG=b:244208960
TEST=test firmware display pass for BOE_TV110C9M_LL0 on Geralt.
