This patch series fixes issues in the dwmac4 driver. These three patches
don't cause any user-visible issues, so they are targeted for net-next.

Patch #1:
Corrects the masking logic in the MTL Operation Mode RTC mask and shift
macros. The current code lacks the use of the ~ operator, which is
necessary to clear the bits properly.

Patch #2:
Addresses inaccuracies in the MTL_OP_MODE_*_MASK macros. The RTC fields
are located in bits [1:0], and this patch ensures the mask and shift
macros use the appropriate values to reflect this.

Patch #3:
Moves the handling of the Receive Watchdog Timeout (RWT) out of the
Abnormal Interrupt Summary (AIS) condition. According to the databook,
the RWT interrupt is not included in the AIS.

Changes since v2:
- Added more description in cover letter.
- Fixed subject for the cover letter

Changes since v1:
- Updated CC list from get_maintainers.pl.
- Removed Fixes tag.
- Add more description in cover letter.
