Copy u-boot sources as is and modify the tree to still build

This patch brings in ipq806x source files from the vendor's u-boot
tree as it was published in the 'cs_banana' release.

The following files are being copied:

arch/arm/cpu/armv7/ipq/clock.c => src/soc/qualcomm/ipq806x/clock.c
arch/arm/cpu/armv7/ipq/gpio.c => src/soc/qualcomm/ipq806x/gpio.c
arch/arm/cpu/armv7/ipq/timer.c =>  src/soc/qualcomm/ipq806x/timer.c
arch/arm/include/asm/arch-ipq806x/clock.h => src/soc/qualcomm/ipq806x/clock.h
arch/arm/include/asm/arch-ipq806x/gpio.h => src/soc/qualcomm/ipq806x/gpio.h
arch/arm/include/asm/arch-ipq806x/gsbi.h => src/soc/qualcomm/ipq806x/gsbi.h
arch/arm/include/asm/arch-ipq806x/iomap.h => src/soc/qualcomm/ipq806x/iomap.h
arch/arm/include/asm/arch-ipq806x/timer.h src/soc/qualcomm/ipq806x/timer.h
arch/arm/include/asm/arch-ipq806x/uart.h => src/soc/qualcomm/ipq806x/uart.h
board/qcom/ipq806x_cdp/ipq806x_cdp.c => src/mainboard/google/storm/cdp.c
board/qcom/ipq806x_cdp/ipq806x_cdp.h => src/soc/qualcomm/ipq8064/cdp.h
drivers/serial/ipq806x_uart.c => src/console/ipq806x_console.c

Note that local timer.c gets overwritten with the original version. To
prevent a build breakage some shortly to be reverted modifications had
to be made to src/soc/qualcomm/ipq806x/Makefile.inc and
src/soc/qualcomm/ipq806x/cbfs.c.
