The ExynosAutov920 SoC includes a PCIe IP and a hsi0 register block that
is mapped in the exynos-sysreg.
To manage PCIe PHY power, configure the PCIe PLL, and set the device direction,
the hsi0 registers need to be defined in exynos-sysreg.
This patch must be applied before the ExynosAutov920 PCIe PHY is enabled.

Add hsi0 compatible for ExynosAutov920 PCIe settings for:
- PCIe PHY power control
- PLL settings for PCIe
- PCIe device direction (RC/EP)
