spi: remove the older/duplicated bcm53xx driver
This driver was added by commit 0fc6a323e1917 ("spi: bcm53xx: driver for SPI controller on Broadcom bcma SoC") back in 2014. It was needed to provide a minimal support for SPI controller on BCM5301X (AKA Northstar) devices. An alternative driver was added by Kamal in commit fa236a7ef2404 ("spi: bcm-qspi: Add Broadcom MSPI driver") 2 years later. It supports the same hardware but for some reason a new driver has been developed for it. At this point the new driver supports: more modes, setting a speed, setting bits per word and uses IRQs instead of polling. DTS file for BCM5301X has also been updated in the commit 1c8f406507238 ("ARM: dts: BCM5301X: convert to iProc QSPI") - over a year ago. That explained I see no reason to keep the old driver alive.
