PMB can be also found on bcm63xx chipsets. It uses difference device
addresses so a new binding is required.

BCM63138 has SATA controller that needs to be powered up using PMB.

Florian: this is based on your patches
ARM: dts: BCM63xx: enable SATA PHY and AHCI controller
reset: bcm63xx: Add Broadcom BCM63138 reset controller driver
I didn't test it as I don't own any bcm63xx devices.
