mtd: bcm47xxpart: lower minimal blocksize to 4Ki (from 64Ki)
Some devices like Netgear WNR1000v3 or WGR614v10 have partitions aligned to 0x1000. Using bigger blocksize stopped us from detecting some parts. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
