Subject: [PATCH v4 02/10] dt-bindings: PCI: brcmstb: Update bindings for PCIe on bcm2712

Update brcmstb PCIe controller bindings with bcm2712 compatible
and add new resets.

Signed-off-by: Stanimir Varbanov <svarbanov@...e.de>

v3 -> v4:
 - Dropped Reviewed-by and Acked-by tags because I have to re-work the patch
   in order to fix newly produced  DTB warnings on the .dts files.
 - Account the number of resets for bcm2712 which are differs from bcm7712.
