Replace separate mask and shift definitions with GENMASK and FIELD_*
macros for better readability and maintainability.

All macros ending in _M have the suffix dropped. The value remains the
same but is now generated with GENMASK. All macros ending in _S are
removed and their uses replaced with FIELD_PREP and FIELD_GET macros.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.
