2017-11-26rockchip: fix turning off boot-mode via KconfigPhilipp Tomsich
The ROCKCHIP_BOOT_MODE_REG option defaults to a hex value, so 0 will show as 0x0 if a default is provided and changed via Kconfig. However, it still will show as 0, if no default is given. Consequently, the "is set to something other than 0" test in a Makefile is cumbersome. Instead this check can easily be performed in the C-code. This removes the ifeq-check from mach-rockchip/Makefile, adds a matching #if-check to boot_mode.c and fixes resulting link issues (if boot_mode.o was not included due to the Makefile check) by defining a stub function (in case the functionality is not built in) for setup_boot_mode in boot_mode.c.

2017-11-21rockchip: make boot_mode related codes reused across all platformsAndy Yan
setup_boot_mode function use the same logic but different mode register address across all the rockchip platforms, so it's better to make this function reused across all the platforms, and let the mode register address setting from the config file.
