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.

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).

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.
