b541dbdf77 serial/stellaris: refactor (again) to conform to driver model
() Renames stellarisUartDrv.c to uart_stellaris.c. This is to follow
   the driver naming convention.
() Renames functions stellaris_uart_*() to uart_stellaris_*(),
   following driver naming convention.
() Renames CONFIG_STELLARIS_UART* to CONFIG_UART_STELLARIS*
() UART ports initialization is moved into the driver itself.
   All the init code in platform config files is removed.
() Adds (many) Kconfig options. These don't have to be defined
   in each platform's board.h anymore.

714dd9786b clock: add Quark SE clock control
Quark SE provides various clock controllers through its SCSS block.
Peripheral, external, sensor, and others.

This current drivers provides only the clock gating capability, for
peripheral, external and sensor. But it could support divider and more
other features once defined in the generic API.

Note: such clock has _nothing_ to do with a Real Time Clock (RTC).
An RTC provide clock timing like a watch would do. Here the clock
controller is about circuit clocking.

5c39418ae8 k20uart: Fix check for Rx/Tx irq
Due to a quirk of the k20 UART, when checking if either a Tx or Rx
irq is ready, one must first check whether the UART has enabled the
Tx and/or Rx interrupts.  If this is not done, then all one is doing
is testing the UART to determine if it is ready to Tx and/or Rx.
