ipq8064/storm: UART enable and various fixes

The original patch from chromium was  a bit of a mishmash.
Between that, rebasing and using the coreboot.org UART infrastructure,
the patch has changed a bit from the original. It seems reasonable to
keep these changes together.
- build in the ipq UART and turn on bootblock console
- sets LPAE and ROM header address
- adds cpd.c to storm

The original commit:
ipq8064: make UART driver work in bootblock

This patch it the last one in the chain adapting the ipq9064 UART
driver for use in coreboot. A new config option
(CONSOLE_SERIAL_IPQ806X) is being introduced to control inclusion of
the driver.

The previously introduced uart_wrapper.c is now included in the build
to provide the console driver structure used by ramstage.

Necessary configuration options are added to allow use of UART in the
bootblock.
