soc: imx: gpcv2: correct PGC offset

[ Upstream commit 3637f12faf507b0a4b8ac1e7115fc99583ab1db3 ]

Correct MIPI/PCIe/USB_HSIC's PGC offset based on
design RTL, the values in the Reference Manual
(Rev. 1, 01/2018 and the older ones) are incorrect.

The correct offset values should be as below:

0x800 ~ 0x83F: PGC for core0 of A7 platform;
0x840 ~ 0x87F: PGC for core1 of A7 platform;
0x880 ~ 0x8BF: PGC for SCU of A7 platform;
0xA00 ~ 0xA3F: PGC for fastmix/megamix;
0xC00 ~ 0xC3F: PGC for MIPI PHY;
0xC40 ~ 0xC7F: PGC for PCIe_PHY;
0xC80 ~ 0xCBF: PGC for USB OTG1 PHY;
0xCC0 ~ 0xCFF: PGC for USB OTG2 PHY;
0xD00 ~ 0xD3F: PGC for USB HSIC PHY;
