[ARM] Fix non-page aligned boot time mappings
AT91SAM9260 stopped booting with the recent changes to MM initialisation - it was asking for a non-aligned virtual address which caused loops to be non-terminal. Fix this by rounding virtual addresses down, but remember to include the offset in the length, and round the length up to the following page. This means that asking for a mapping of 4K starting at 2K into a page maps two pages as one would expect. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
