powerpc: spl: configure SYS_MALLOC_F_LEN independently for SPL and full U-Boot

Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

powerpc/mpc85xx: T104x: Add nand secure boot target

For mpc85xx SoCs, the core begins execution from address 0xFFFFFFFC.
In non-secure boot scenario from NAND, this address will map to CPC
configured as SRAM. But in case of secure boot, this default address
always maps to IBR (Internal Boot ROM).
The IBR code requires that the bootloader(U-boot) must lie in 0 to 3.5G
address space i.e. 0x0 - 0xDFFFFFFF.

For secure boot target from NAND, the text base for SPL is kept same as
non-secure boot target i.e. 0xFFFx_xxxx but the SPL U-boot binary will
be copied to CPC configured as SRAM with address in 0-3.5G(0xBFFC_0000)
As a the virtual and physical address of CPC would be different. The
virtual address 0xFFFx_xxxx needs to be mapped to physical address
0xBFFx_xxxx.

Create a new PBI file to configure CPC as SRAM with address 0xBFFC0000
and update DCFG SCRTACH1 register with location of Header required for
secure boot.

The changes are similar to

powerpc/mpc85xx: SECURE BOOT- NAND secure boot target for P3041

While P3041 has a 1MB CPC and does not require SPL. On T104x, CPC
is only 256K and thus SPL framework is used.
The changes are only applicable for SPL U-Boot running out of CPC SRAM
and not the next level U-Boot loaded on DDR.

powerpc/mpc85xx: Use GOT when loading IVORs post-relocation

Commit 96d2bb952bb ("powerpc/mpc85xx: Don't relocate exception vectors")
simplified IVOR initialization a bit too much, failing to use the
post-relocation offset. This doesn't cause a problem with normal NOR
boot, in which both the pre-relocation and post-relocation addresses
are 64 KiB aligned. However, if TEXT_BASE is only 4 KiB aligned, such
as for NAND/SD/etc. boot on some targets, as well as the QEMU target,
the post-relocation address will not be the same in the lower 16 bits,
as reserve_uboot() ensures that the relocation address is always 64
KiB aligned even if the pre-relocation address was not.

Use the GOT to get the proper post-relocation offsets.
