bcm53xx: switch to m25p80 and drop bcm53xxspiflash
For some time now m25p80 supports 32 MiB flashes and we just needed to patch spi-nor to support JEDEC incompatible w25q128. Also by switching to m25p80 we gain accelerated SPI flash reads. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 49260
