pinctrl: pinctrl-aspeed-g6: remove FWQSPID group in pinctrl

[ Upstream commit 3eef2f48 ]

FWSPIDQ2 and FWSPIDQ3 are not part of FWSPI18 interface so remove
FWQSPID group in pinctrl. These pins must be used with the FWSPI
pins that are dedicated for boot SPI interface which provides
same 3.3v logic level.
