bugfix: all Marvell specific build fails due to undefined reference to `get_ticks'

after http://patchwork.ozlabs.org/patch/136415/ was applied. All Marvell
build fails with below error

common/libcommon.o: In function `cread_line':
/home/uboot/src/u-boot-arm/common/main.c:717: undefined reference to `get_ticks'
/home/uboot/src/u-boot-arm/common/main.c:717: undefined reference to `get_tbclk'
/home/uboot/src/u-boot-arm/common/main.c:720: undefined reference to `get_ticks'

The same is fixed for Kirkwood, ARMADA100, pantheon and orion5x SoCs
