Subject: FMUv2: make all UARTs use 512 byte buffer, 2048 for CDCACM output

this is important when using UARTs for things like secondary GPS
modules, which may produce large enough transfers that 128 bytes is
not enough.

The 2048 buffer for CDCACM transmit makes mavlink log and parameter
transfer faster
