Heinrich Schuchardt b6701e556f riscv64: ensure reasonable partition alignment
Currently the RISC-V preinstalled server images come with partitions that
are only 1 KiB aligned. Ext4 may use 4 KiB block size. The existing
misalignment leads to decreased performance.

Decrease the size of the loader2 partition by 34 512-byte blocks. This
results in 1 MiB alignment of the EFI and root partitions.

The remaining loader2 partition size of close to 4 MiB is still large
enough for U-Boot or a future EDK II.

Fixes: a808b28d47ec ("riscv64: build preinstalled riscv64 image with uboot SPL and CIDATA.")
