From: Sui Jingfeng <suijingfeng@xxxxxxxxxxx>
Because the etnaviv_gem_new_private() function receives the size_t argument
for the number of pages. And the number of pages should be unsigned.
Note that Most 32-bit architectures use "unsigned int" size_t,
and all 64-bit architectures use "unsigned long" size_t.
So, let's keep the argument and parameter consistent.
