veyron_*: Move PMIC_BUS to a Kconfig variable

This moves PMIC_BUS from each mainboard's board.h file to a per-
mainboard Kconfig variable. To prevent humans from forgetting to
set a valid value, an invalid default is set in the rk3288 Kconfig
and checked in rk808.c so that compilation will fail if the mainboard
Kconfig does not override it.

Originally, PMIC_BUS was only used by mainboard code as an argument
to RK808 PMIC functions. To conform to the generic RTC API, however,
the RK808 code needs to have the bus number globally defined somewhere
since the rtc_get() and rtc_set() functions don't take any args.

Since CONFIG_PMIC_BUS is globally visible, we no longer need to pass
bus number to the PMIC functions.
