roms/u-boot: Bump ppce500 u-boot to v2021.04 to fix broken pci support
When QEMU originally supported the ppce500 machine back in Jan 2014,
it was created with a 1:1 mapping of PCI bus address. Things seemed
to change rapidly that in Nov 2014 with the following QEMU commits:
commit e6b4e5f4795b ("PPC: e500: Move CCSR and MMIO space to upper end of address space")
and
commit cb3778a0455a ("PPC: e500 pci host: Add support for ATMUs")
the PCI memory and IO physical address were moved to beyond 4 GiB,
but PCI bus address remained below 4 GiB, hence a non-identity
mapping was created. Unfortunately corresponding U-Boot updates
were missed along with the QEMU changes and the U-Boot QEMU ppce500
PCI support has been broken since then, until this issue was fixed
recently in U-Boot mainline v2021.04 release, specifically by the
following U-Boot series:

The cross-compilation toolchain used to build the U-Boot image is:
