As modem receiver is using UART, it requires disabling
of the UART and its callbacks to save power.
This adds simple sleep/wake functions which should be
called from defined device_pm functions in modem drivers later.

move uart.h to drivers/uart.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

Move modem_receiver.h to the driver directory. No other users in the
tree and it is a private header.

mdm_receiver_send() was sending 1 too many bytes of buf. This ended
up being the NULL terminator. Size should be reduced prior to the
while check so that this doesn't happen.

LOG_LEVEL should be set to CONFIG_MODEM_LOG_LEVEL not
CONFIG_LOG_MODEM_LEVEL. In cleaning this up use
LOG_MODULE_REGISTER(x,y) form to reduce 3 lines to 1.

Modem drivers need a fast buffer-based receiver for passing data
back and forth from the UART to the driver. This provides an
efficient configuarable driver which merely sends and receives
but doesn't process the data, that's left up to the modem driver.
