Subject: [PATCH v2 0/2] Add support for AM62P SR1.2

This patch series adds support for the AM62P SR1.2 silicon revision by
adding logic in k3-socinfo to detect AM62P variants.

This also disables HS400 support for AM62P SR1.0 and SR1.1 in sdhci host
driver and enable by default for AM62P SR1.2.

Tested against AM62P SR1.2, SR1.1, SR1.0 and AM62X SK.
Log for AM62P SR1.2:
https://gist.github.com/jmenti/3d605dcd9445c2fac86c626bfa519103

Changes since v1:
- Drop binding and DT patches 
- Move disable HS400 print to sdhci_am654_init & only print if caps are
  already enabled, according to Andrew's review
- Completely refactor/change patch 2/4 for k3-socinfo to not add a new
  item to reg property, find GP_SW as an offset of JTAG ID. This approach
  is based off-of Krzysztof's review.
