Subject: [PATCH] rtw88: Remove set but not used variable 'ip_sel' and 'orig'

Fixes gcc '-Wunused-but-set-variable' warnings:

drivers/net/wireless/realtek/rtw88/pci.c: In function rtw_pci_phy_cfg:
drivers/net/wireless/realtek/rtw88/pci.c:978:6: warning: variable ip_sel set but not used [-Wunused-but-set-variable]
drivers/net/wireless/realtek/rtw88/phy.c: In function phy_tx_power_limit_config:
drivers/net/wireless/realtek/rtw88/phy.c:1607:11: warning: variable orig set but not used [-Wunused-but-set-variable]

They are never used, so can be removed.
