[PATCH] staging: fpga manager: fix array_size.cocci warnings

[kbuild test robot <fengguang.wu@intel.com>]

drivers/staging/fpga/altera.c:368:33-34: WARNING: Use ARRAY_SIZE

 Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element

Semantic patch information:
 This makes an effort to find cases where ARRAY_SIZE can be used such as
 where there is a division of sizeof the array by the sizeof its first
 element or by any indexed element or the element type. It replaces the
 division of the two sizeofs by ARRAY_SIZE.
