exynos5420: Alter init sequence as per recommendation

As per hardware recommendation, CKE PAD retention release must
    happen just before gate leveling enable and only in case of resume.
    Hence, this patch moves pad retention release from dmc_common.c to
    dmc_init_ddr3_exynos5420.c. In addition to this we are providing
    125 (+3 extra being safe) times auto refresh to DRAM by sending
    REFA direct command. This is required because when CKE PAD retention
    release happens, self refresh mode of DDR3 is disabled.
    Hence, auto refresh 125 times.

This is ported from https://gerrit.chromium.org/gerrit/#/c/65573

Note: Since WAKEUP_DIRECT does not go thru memory init, it should be
    safe to move CKE PAD retention out of bootblock.c.
