media: atomisp: Fix a spelling mistake in sh_css_defs.h

The script checkpatch.pl reported a spelling error
in sh_css_defs.h as below:

'''
WARNING: 'upto' may be misspelled - perhaps 'up to'?
/* The FPGA system (vec_nelems == 16) only supports upto 5MP */
                                                    ^^^^
'''

This patch corrects a spelling error,
changing "upto" to "up to".
