[patch] backlight: s6e63m0: report ->gamma_table_count correctly

[Dan Carpenter <dan.carpenter@oracle.com>]

gamma_table has 3 arrays which each hold MAX_GAMMA_LEVEL pointers to
int.

The current code sets ->gamma_table_count to 6 on 64bit arches and to 3
on 32 bit arches.  It should be 3 on everything.

This is from reading the code.  We use ->gamma_table_count in sysfs file
but other than that I'm not sure what it's for.  I am not very familiar
with this code.
