Subject: [PATCH v3 0/4] arm64: dts: ti: Modify pinmux for wkup_uart0 and mcu_uart0

WKUP_PADCONFIG registers for wkup_uart0 and mcu_uart0 lies under
wkup_pmx2 for J7200. Thus, modify pinmux for both of them. Also,
remove the redundant clock-frequency property from mcu_uart0 node.

Only Tx and Rx Signal lines for wkup_uart0 are brought out on
J721S2 Common Proc Board and J784S4 EVM, but CTS and RTS signal lines
are not brought out. Thus, remove pinmux for CTS and RTS signal lines
for wkup_uart0 in J721S2 and J784S4.

v2 Link : https://lore.kernel.org/all/20240212104417.1058993-1-b-kapoor@ti.com/

Changelog v1->v2:
 - Divided Pinmux and clock frequency patch(1/3) for J7200 into 2 patches
 - Change commit message to include wkup_uart0 for referring to the instance

Changelog v1->v2:
 - Added Fixes tag in Commit message
