arm64 cannot represent the kernel VAs in HYP mode, because of the lack of TTBR1 at EL2. A way to cope with this situation is to have HYP VAs to be an offset from the kernel VAs. Introduce macros to convert a kernel VA to a HYP VA, make the HYP mapping functions use these conversion macros. Also change the documentation to reflect the existence of the offset. On ARM, where we can have an identity mapping between kernel and HYP, the macros are without any effect. Signed-off-by: NMarc Zyngier <marc.zyngier@arm.com>

On 32bit ARM, unsigned long is guaranteed to be a 32bit quantity. On 64bit ARM, it is a 64bit quantity. In order to be able to share code between the two architectures, convert the registers to be unsigned long, so the core code can be oblivious of the change.

This patch adds an SPI master device node for Armada XP-GP board. This master node is an SPI flash controller 'n25q128a13'. Since there is no 'partitions' node declared, one full sized partition named as the device will be created.
