Subject: [PATCH v2 0/6] arm64: dts: meson-g12: add support for PCIe

This patchset :
- updates the Amlogic PCI bindings for G12A
- reworks the Amlogic PCIe driver to make use of the
G12a USB3+PCIe Combo PHY instead of directly writing in
the PHY register
- adds the necessary operations to the G12a USB3+PCIe Combo PHY driver
- adds the PCIe Node for G12A, G12B and SM1 SoCs
- adds the commented support for the S922X, A311D and S905D3 based
VIM3 boards.

The VIM3 schematic can be found at [1].

This patchset is dependent on Remi's "Fix reset assertion via gpio descriptor"
patch at [2].

This patchset has been tested in a A311D VIM3 and S905D3 VIM3L using a
128Go TS128GMTE110S NVMe PCIe module.

For indication, here is a bonnie++ run as ext4 formatted on the VIM3:

  4G 93865  99 312837  96 194487  23 102808  97 415501 21 +++++ +++

and the S905D3 VIM3L version:
     ------Sequential Output------ --Sequential Input- --Random-
     -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks--
Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP  /sec %CP
  4G 52144  95 71766  21 47302  10 57078  98 415469  44 +++++ +++

Changes since v1 at [3]:
 - Collected Andrew's and Rob's Reviewed-by tags
 - Added missing calls to phy_init/phy_exit
 - Fixes has_shared_phy handling for MIPI clock
 - Add comment in the DT concerning firmware setting the right properties
 - Added SM1 Power Domain to PCIe node
