media: atomisp: Fix spelling mistake in ia_css_acc_types.h

codespell reported spelling mistakes in
ia_css_acc_types.h as below:

'''
ia_css_acc_types.h:87: cummulative ==> cumulative
ia_css_acc_types.h:411: descibes ==> describes
'''

This patch fixes these spelling mistakes.
Word "cummulative" is changed to "accumulation"
and "descibes" to "describes".
