Subject: [PATCH v2] ARM: dts: aspeed: update Hr855xg2 device tree
Update i2c aliases.
Change flash_memory mapping address and size.
Add in a gpio-keys section.
Add in a peci0 section.
Update i2c0,i2c0 and i2c11 section.
Enable vhub, vuart, spi1 and spi2.
Remove gpio from gpio section since it controlled by user space.

Changes in v2:
- remove spidev@0 property.
- remove espi-enabled property.
- add a space for switch0_i2c5:i2c@5.
- dropping CPUXX_VCCXX and VR pmbus relative property.
