Intel Quark has DesignWare UART. Move the code from 8250_pci to
8250_lpss.

Andy,

If you are going to start removing working PCI devices from the PCI
config table in favour of a shim in SERIAL_8250_LPSS then the very
minimum should be some sort of dependency link between SERIAL_8250_LPSS
and CONFIG_SERIAL_8250_PCI in kconfig.

A user could reasonably read the QRK datasheet - switch on
CONFIG_SERIAL_8250_PCI and then wonder why no console output happened
on boot. S/he shouldn't have to know that devices were moved from the
PCI driver to an LPSS shim driver or that the 8250_lpss driver now
needs to be selected instead of the intuitively correct 8250_pci
driver.

So assuming you agree with that (profound and sublime) logic and will
make that dependency linkage then this is fine for me from a QRK POV.
