This series fixes and enables PCIe and NVMe support on RK3568.
Patch 1 adds a dev_read_addr_size_index_ptr function.
Patch 2-3 fixes main issue in the driver to be usable on RK3568.
Patch 4 fixes a long wait time during probe when no device is attached.
Patch 5 disable BARs of the root complex that could claim the entire
memory region during PCI autoconfig.
Patch 6 adds support for the gpios prop to the fixed regulators driver.
Patch 7 adds a missing clock to the clock driver.
Patch 8 enables PCIe and NVMe support on rk3568-rock-3a.
Patch 9 updates the device tree with new reg and ranges values.
I have tested that a Samsung 970 EVO NVMe is detected on a ROCK 3A,

and I have also verified that the network controller continues to be
detected on a ROCK 5B.

Changes in v4:
- Replace "Hide BARs of the root complex" with "Disable unused BARs of
the root complex" patch, based on vendor commit 1f4523203c2a ("driver:
pci: rockchip: Disable RC BAR0 and BAR1")
Changed in v3:
- Rebased on master branch, all dependencies has been merged.
- Remove rk3568-rock-3a pcie2x1 workaround added in v2, basic reference
counting of gpio regulators series has been merged.
- Enable options for AHCI/SCSI on rk3568-rock-3a.
- Collect r-b tags.
Changes in v2:
- Rebased on custodians/u-boot-rockchip master branch and the defconfig
and spi v2 series at [1].
- Drop dependency on basic reference counting of gpio regulators series,
pcie2x1 is disabled for rk3568-rock-3a to avoid a system freeze due to
disable of a shared vpcie3v3-supply regulator while in use by pcie3x2.
- Add and use dev_read_addr_size_index_ptr function.
- Update commit messages.
- Collect r-b tags.
