[linux-yocto][v6.1/standard/nxp-sdk-6.1/nxp-soc & v6.1/standard/preempt-rt/nxp-sdk-6.1/nxp-soc][PATCH] soc: imx8mp: place read register before clk_disable_unprepare()
commit 328efccc7847 ("soc: imx8m: Enable OCOTP clock for imx8mm
before reading registers") has re-enabled the clock, so reading
the registers needs to be done before clk_disable_unprepare(),
otherwise the kernel will hang.
Fixes a3985483e7f1 ("LF-9486 soc: imx8mp: support 128 bits UID")
