media: si2157: use a different namespace for firmware
Each chip at the si21xx TER family seems to have a different firmware, with seems to actually be a patch against the ROM code. Rework the code in order to use different firmware files depending on the chip ID and rom ID. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
