ARM: dts: aspeed: Grow u-boot partition 64MiB OpenBMC flash layout

Aspeed AST2600 u-boot requires 600KiB+ flash space. Sharing the same
openbmc-flash-layout-64.dtsi requires to resize the flash partition.

The updated flash layout as follows:
- u-boot: 896 KiB
- u-boot-env: 128 KiB
- kernel: 9MiB
- rofs: 32 MiB
- rwfs: 22 MiB
