XMC4xxx: Simply some USIC logic, add USIC interface to disable a channel.  Add USIC enable logic to UART configuration (a lot more to do there).

STM32F3: Add COMP support

Approved-by: Gregory Nutt <gnutt@nuttx.org>

XMC4xxx: Revise configuration for USICs.  Three USICs but 4 UARTs possible with each channel of USIC.

mtd/progmem: fix incorrect target address calculation

STM32F33: Move DMA logic to a separate files + add ADC support

Approved-by: Gregory Nutt <gnutt@nuttx.org>

progmem_read/write() is incorrectly calculating the target address,
expecting the offset argument is given in a block number. This is
completely wrong and as a result invalid flash region is accessed.
Byte-oriented read/write interfaces of mtd device accept the
target address in a byte offset, not a block number.
