ramips: fix ralink_default_fw_size_16M
In ramips, there are the following predefined values for IMAGE_SIZE
ralink_default_fw_size_4M
3866624 3776k 0x3B0000
ralink_default_fw_size_8M
8060928 7872k 0x7B0000
ralink_default_fw_size_16M
16121856 15744k 0xF60000
ralink_default_fw_size_32M
33226752 32448k 0x1FB0000
Out of those, the "16M" value is obviously odd, as it provides more
room for the remaining partitions than the tree others.
Of the devices in all subtargets, there are actually > 50 that have
a firmware partition with 0xFB0000 size, while only 5 (!) have
0xF60000. From the former, many are set to
ralink_default_fw_size_16M anyway, although it is wrong at the
present point.
Consequently, it makes sense to change ralink_default_fw_size_16M
to 0xFB0000, and to update IMAGE_SIZE for the 5 devices with
0xF60000.
