lkl: follow up fix after v6.6 merge (PAGE_SHIFT)

Browse Source 
As nommu architecture uses __va definition in asm-generic, it is casted
with (void*) after the macro.  But pfn_to_virt definition is using shift
operation after the cast so, compilers raise warnings/errors/

I suppose this is an upstream bug when they introduce the commit.

Fixes: 2d78057f0d ("asm-generic/page.h: Make pfn accessors static inlines")
