meta-ampere: mtjade: replace u-boot patches by feature

Enable phosphor-aspeed-spi-master-mode.inc and remove the u-boot
patch that used for this feature.
Also remove GPIO setting patches which the setting already implemented
in the platform init package.

Tested: on Mt.Jade platform with OCP plugged
1. Bind/unbind Host SPI-NOR and ensure no problem
2. Turn off Host, reboot BMC and check if Host SPI-NOR is probe
successfully.
