[PATCH v2] arm64: dts: ti: k3-j721s2-som-p0: Correct pinmux offset for ospi0

[Udit Kumar]

Due to non-addressable regions in J721S2 SOC wkup_pmx was split
into four regions from wkup_pmx0 to wkup_pmx3.

After split while updating the pin mux references to newly defined
four wkup_pmx, pin mux for OSPI0 was left.

Pin mux for OSPI0 is spread over two range wkup_pmx0
and wkup_pmx1, along with correcting pin mux for ospi
adding correct pin mux setting within ospi node.

Fixes: 6bc829ceea41 ("arm64: dts: ti: k3-j721s2: Fix wkup pinmux range")
