This pull request contains defconfig changes for Broadcom ARM-based SoCs:

- Florian enables support for the BCM63xx DSL SoCs basic peripherals, enables
  the networking subsystems for Set Top Box SoCs, enables the PWM, watchdog and
  the AHCI controller and SATA PHY drivers

- Florian removes the bcm_defconfig file which is no longer useful and updates
  multi_v7_defconfig to include the Kona watchdog to provide proper reboot for the
  Broadcom Kona platforms

Please note that Tejun Heo has queued a patch which renames AHCI_BRCMSTB into
AHCI_BRCM, to avoid two patches in a row, we just enable AHCI_BRCM to be future
proof
