qemu_v8: u-boot: fix load address of kernel and RAM disk

[jforissier]

This commit changes the load address of the kernel and of the RAM disk when U-Boot is used (make UBOOT=y). It fixes the following boot error with v2023.07.02:

Reading file would overwrite reserved memory

• The kernel load address, ${kernel_addr_r}, is moved from 0x40400000 (the default defined in u-boot/board/emulation/qemu-arm/qemu-arm.env) to 0x42200000 because the current kernel size is too big to fit in the available space: 0x40400000 + 38783552 (current uImage size, ~37 M) = 0x446FCA40 Output of the U-Boot 'bdinfo': => bdinfo ... lmb_dump_all: memory.cnt = 0x1 / max = 0x10 memory[0] [0x40000000-0x820fffff], 0x42100000 bytes flags: 0 reserved.cnt = 0x4 / max = 0x10 reserved[0] [0xe100000-0xeffffff], 0x00f00000 bytes flags: 4 reserved[1] [0x42000000-0x421fffff], 0x00200000 bytes flags: 4 reserved[2] [0x7f99b000-0x820fffff], 0x02765000 bytes flags: 0 reserved[3] [0x8099b3e0-0x820fffff], 0x01764c20 bytes flags: 0 There is indeed an overlap with reserved[1].
• The RAM disk is loaded at 0x44000000 by default (${ramdisk_addr_r}). With the above change it needs to be moved to a higher address, after the end of the kernel (0x446FCA40). Let's take some margin and choose 0x45000000.

Depends on https://github.com/OP-TEE/manifest/pull/243 which needs to be merged first.
