The patch series enables he OSPI1 aka QSPI node.
This is a precursor for enabling QSPI boot on j721e.
Keerthy (3):
arm: dts: k3-j721e-common-proc-board-u-boot: Enable ospi1/qspi
arm: dts: k3-j721e-mcu-wakeup: Add assigned-clocks/rates properties
for ospi1/qspi

Enable the ospi1/qspi module while at it move the corresponding
pins to common u-boot.dtsi file.

Add assigned-clocks/rates properties for ospi1/qspi.
This is the expected rate as per ROM configuration.

pinmux should be in k3-j721e-common-proc-board.dts like in kernel DT.
Replicate the pinmux in R5 dts file for use in R5 SPL.
Only u-boot specific property "u-boot,dm-spl" should be added in
k3-j721e-common-proc-board-u-boot.dtsi

No need to for status = "okay" as OSPI1 is enabled by default.
