mm/memremap: Replace zero-length array with DECLARE_FLEX_ARRAY() helper
Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length array
declaration in struct dev_pagemap with the new DECLARE_FLEX_ARRAY()
helper macro.
This helper allows for a flexible-array member in a union.
Also, this addresses multiple warnings reported when building
with Clang-15 and -Wzero-length-array.
