This patch contains the following cleanups:
- make needlessly global functions static
- move arcmsr_scsi_host_template from arcmsr.h to arcmsr.c
(code doesn't belong into header files)

Signed-off-by: Adrian Bunk <bunk@xxxxxxxxx>

---

Some notes:
- BOOLEAN/TRUE/FALSE, own get_min/get_max aren't kernel coding style
- the own subdirectory for this driver seems to be overkill
- aren't the "if defined(__x86_64__)" wrong for other 64bit
architectures?
