alpha: use L1_CACHE_BYTES for cacheline size in the linker script
Currently the linker script uses 64 for cacheline size which isn't optimal for all cases. Include asm/cache.h and use L1_CACHE_BYTES instead as suggested by Sam Ravnborg. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Sam Ravnborg <sam@ravnborg.org>
