ARM: fix CONFIG_VIRT_TO_BUS handling
887cbce0 "arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS" and 4febd95a8 "Select VIRT_TO_BUS directly where needed" from Stephen Rothwell changed globally how CONFIG_VIRT_TO_BUS is selected, while my own a5d533ee0 "ARM: disable virt_to_bus/ virt_to_bus almost everywhere" was merged at the same time and changed which platforms select it on ARM. The result of this conflict was that we again see CONFIG_VIRT_TO_BUS on all ARM systems. This patch fixes up the problem and removes CONFIG_ARCH_NO_VIRT_TO_BUS again on ARM.
