apollolake: Remove timing delay for SOC_PWROK and RSMRST_N
apollolake: Remove timing delay for SOC_PWROK and RSMRST_N

PMIC already has a built-in 100ms delay for V1P05S when ALL_SYS_PWRGD
asserts, hence EC can assert SOC_PWROK immediately. On shutdown RSMRST_N
should assert and SOC_PWR_OK should de-assert immediately when PMIC asserts
PMIC_RSMRST_N and de-assert All_SYS_PWRGD respectively. Hence removed
the unnecessary timing delay for SOC_PWROK and RSMRST_N.

BUG=none
BRANCH=none
TEST=Issued a shutdown command and manually tested on amenia.
     RSMRST_N asserts immediately when PMIC asserts PMIC_RSMRST_N
     SOC_PWR_OK de-asserts immediately when PMIC de-asserts All_SYS_PWRGD.
