drivers:ufs: fix hynix ufs bug with quirk on hi36xx SoC
Hynix ufs has deviations on hi36xx platform which will result
in ufs bursts transfer failures at a very low probability.
To fix the problem, the Hynix device must set the register
VS_DebugSaveConfigTime to 0x10, which will set time reference
for SaveConfigTime is 250 ns. The time reference for SaveConfigTime
is 40 ns by default.
