ARM: simplify early machine init hooks
Rather than storing each machine init hook separately, store a pointer to the machine description record and dereference this instead. This pointer is only available while the init sections are present, which is not a problem as we only use it from init code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
