Found the lposc fuse loading having impact to cpu idle in kernel.
Without the loading in dual boot mode, kernel will hang after idle
for a while.

Assign the LPAV owner to RTD, and assign LPAV masters and peripherals
to APD. So except the masters and peripherals, other resources
(like DDR, cgc2, pcc5) in LPAV won't be reset during reboot and suspend.
No needs to initialize DDR again after reboot.

the previous method not enable MU0_B clk and not able to communicate

And we not put it under kernel dts, because it conflicts with i.MX8QM

When reset with dual boot mode, the LPAV domain won't power down
due to its master is not assigned to APD. So the NICLPAV keeps the
last setting to use PLL4PFD1. So before SPL initialize the PLL4,
we need to switch NICLPAV to FRO192, otherwise system will hang.

When M33 is LPAV owner in dual boot, DDR, PCC5, CGC2 won't be reset

The mxs_nand_spl driver can support to read from page unaligned offset,
so don't need to set bl_len to ask spl_load_simple_fit to handle
the page unaligned access.
Actually spl_load_simple_fit has two parts of reading:
spl_simple_fit_read and spl_load_fit_image.
The spl_load_fit_image can handle the page unaligned offset,
but the spl_simple_fit_read can't do it. spl_simple_fit_read requires
the FIT location at page aligned offset.
Hence, remove the nand_get_mtd overwrite function from mxs_nand_spl
to use page unaligned read by driver.
