wifi: rtw89: phy: add phy_gen_def::cr_base to support WiFi 7 chips

cr_base is base address of PHY control register. The base of WiFi 6 and 7
chips are 0x1_0000 and 0x2_0000 respectively, so define them accordingly.
For example, if PHY address is 0x1330, absolute address is 0x1_1330 for
WiFi 6 chips, and 0x2_1330 for WiFi 7 chips.

Meanwhile, there are two copies of PHY hardware named PHY0 and PHY1. The
offset between them is 0x2_0000, so the base address of PHY0 and PHY1 are
0x2_0000 and 0x4_0000 respectively.
