Subject: [PATCH v2] Fix pointer cast for 32 bits arch

Sparse compalins about casting void * to u64 on i386.
Change the cast to resource_size_t.

Also update the gf_write64 function definition changing
the first argument type from unsigned long data to
resource_size_t.

Changes from V1:
- Updated commit message.

Tested by compilation only. Tested for x86 and x86_64.
