retimer: Adjust delay after taking BB/HB out of reset
This CL increases the delay in the power enable routine after taking
the retimer out of reset. Without this additional delay, the first
read of HB will fail.
BRANCH=none
BUG=b:244874682
TEST=Verifed that after increasing the delay, the errors seen reading
the HB retimer following the power_enable call are resolved.
