wcnss: Add WMAC registers to register dump list

When a WDI timeout or Watchdog bite happens at WCNSS, certain WCNSS
registers are logged for debug purpose. Add WLAN domain registers
TXP PHY aborts and MCU WLAN bridge error timeout registers to this
list. This is helpful for debugging the A2XB split timeout issues.
