Rafał Miłecki ed00387dc5 bcm53xx: switch to the new/alternative SPI controller driver
This switches bcm53xx from spi-bcm53xx to the spi-bcm-qspi driver. The
later one was developed by Broadcom and is more advanced one. It
supports more modes, setting a speed, setting bits per word and uses
IRQs instead of polling.

This increases kernel size from 1808120 B to the 1811160 B (by 3040 B).
