[PATCH v2] arm64: dts: ti: k3-j784s4-evm: Correct Pin mux offset for ospi

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

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

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