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).

f5195e72c0 kernel: mtd: bcm47xxpart: improve handling TRX partition size
This is important fix for flash parsing in some corner cases. In case
of TRX subpartition with rootfs being aligned to the flash block size it
was incorrectly registered twice. Detecting & registering it as a
standalone partition was resulting in an incorrect "firmware" partition
size and possibly broken sysupgrade.

It wasn't noticed before because "rootfs" alignment depends on a kernel
size. It can happen though - depending on the configuration and the
kernel size.

05cb6aa69f bcm53xx: replace linux,part-probe with a proper partitions subnode
This solution is more upstream compatible as it only requires specifying
of_match_table in the parser code and doesn't depend on linux,part-probe
which is solution made generic by a LEDE downstream patch that can't be
upstreamed.
