Subject: [PATCH] arm64: dts: ti: k3-j784s4-evm: Correct Pin mux offset for ADC

After splitting wkup_pmx pin mux for J784S4 into four regions.
Pin mux offset for ADC nodes were not updated to align with new
regions, due to this while probing ADC driver out of range
error was seen.

Pin mux offsets for ADC nodes are corrected in this patch.

Fixes: 14462bd0b247 ("arm64: dts: ti: k3-j784s4: Fix wakeup pinmux range and pinctrl node offsets")

Reviewed pin mux for J784S4-EVM, AM69, J721S2-EVM and AM68
ADC seems to be last one to be fixed.

In order to test this patch
following drivers were built in as part of kernel
CONFIG_MFD_TI_AM335X_TSCADC=y
CONFIG_TI_AM335X_ADC=y

dtbs_check is done after applying
