USART_CR1_M combines both USART_CR1_M0 and USART_CR1_M1 macros
affecting bits 12 and 28 on 7 data bits capable UARTs. Whereas
for other UARTs USART_CR1_M macro affects only bit 12.
This patch fixes wrong data bits usage on 7 data bits capable
UARTs with using USART_CR1_M0 macro for modes 8-E-x and 8-O-x.
It also simplifies bits unsetting as USART_CR1_M macro clears
all data bits related bits for both UART types.

In UniFlash 4.4.0 the directory where 'xds110reset' is changed.
Try to use the newest one available. If none is found in UNIFLASH_PATH,
try to use one from the PATH to be sure to have a value.

The timer_clear function doesn't clear the hardware timer counter, but
is designed to clear the allocation of the channel. The consequence is
that the IFS timer here is not set to zero in the callback, but only
stopped at the current value. When the timer is started again, it has to
count the full timer range until it matches the timeout value again.
This commit fixes this issue by using timer_set instead of
timer_set_absolute. This way the current timer value (when the timer is
stopped) is read and the IFS timeout value is added to the current timer
value.
ieee802.15.4 specifies 40 symbols as LIFS value and 12 symbols as SIFS
value. Furthermore, the 2.4Ghz DSSS mode has a symbol rate of
62.5Ksymbols/s. To have the LIFS and SIFS in the code match the timings
from the specification, the TIMER_FREQ must match the symbol rate of
62.5Ksymbol/s such that one tick of the timer equals one symbol in time.
This commit adds usbdev, a common API to interface USB peripheral
devices. The API is split into two parts, one for the USB device itself
and one for the USB endpoint.
Add a rule to build `lpc2k_pgm` when flashing.
It is only compiled if it is using the one in `tools`.
If overwritten to `lpc2k_pgm` if it should be taken from the path,
it is not compiled.
The compilation is still done in `boards/common/msba2/tools` as it was
the case before and this commit does not address this.
Added arduino-nano to BOARD_INSUFFICIENT_MEMORY/BOARD_BLACKLIST following suit
of how arduino-uno is marked, as arduino-nano is mostly an Uno in a different
form factor.
According to the documentation of `gnrc_ipv6_nib_get_next_hop_l2addr()`
`pkt` may be `NULL`. However, whenever that function sends an error
message (the methods for that require `orig_pkt` not to be NULL) `pkt`
is not checked, which may lead to failed assertions.
