[PATCH 0/8] Enable PCIE controller on iMX95 EVK

[Ye Li]

The patch set is used to enable PCIE host controller on iMX95 EVK.
We need below driver changes:
1. Add iMX95 support to pcie_dw_imx driver.
2. Add iXM95 blkctrl clock driver which is a abstract of clock gate
   in hsio blkctrl for PCIE.
3. Add vin-supply enablement for fixed regulator, since iMX95 EVK
   uses two levels regulators in DTS.
4. Fix issue in clk-uclass when assign high clock rate.
