soc/mediatek/mt8183: Use cached calibration result for faster bootup

Load calibration params from flash. If the format of the params is
correct, use these calibration params for fast calibration to reduce the
bootup time.

Bootup time of DRAM partial calibration:
 - 1,349,385 usecs with low frequency
 -   924,698 usecs with middle frequency
 - 1,270,089 usecs with high frequency
3,544,172 usecs in total.

Bootup time of DRAM fast calibration:
 - 216,663 usecs with low frequency
 - 328,220 usecs with middle frequency
 - 322,612 usecs with high frequency
867,495 usecs in total.

BUG=b:139099592
BRANCH=none
TEST=Boots correctly on Kukui
