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.

USB Host driver for the XBox One game controller

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

Adds driver support for the XBox One controller.  Currently only the latest version (XBox One X) controller works.  The older XBox One controllers do not enumerate correctly.

vsnprintf(): If size is zero, then vsnprintf() should return the size of the required buffer without writing anything.  This is same fix that was done for snprintf in 2014 by commit 59846a8f.

libc: printf: fix precision for string formatting. Fixes use of format precision to truncate input string.
