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).
