This patch fixes the QMSI UART shim driver so we are able to use it in
Quark D2000 based platforms. Differently from Quark SE, the peripheral
clock gate bit (CLK_PERIPH_CLK) is not enabled by default in Quark
D2000. We have to explicitly set this bit in order to properly initialize
the device.
Since this drivers is now properly working on Quark D2000, this patch
also sets the QMSI driver default options in arch/x86/soc/quark_d2000/
Kconfig.
