phy/usddrphy: use ic reset (to be sure to follow UG571's reset sequence) and use VAR_LOAD mode on DQS's ODELAYE3.
...
This fixes some reset issues seen on some boards (seen when deployed on large systems with > 100 different boards/controllers),
and avoid having to reload DQS delay from software on DQS reset.

phy/usddrphy: simplify tCK reference by using a specific ODELAYE3 in FIXED mode and keep the PHY in reset by default.

Keeping the PHY in reset by default was not possible previously due to the ODELAYE3 configuration
that was lost on reset. Using a specific ODELAYE3 in FIXED mode allow keeping the PHY in reset at
startup.
