Thomas Monjalon 924e6b7634 drivers: replace page size definitions with function 
The page size is often retrieved from the macro PAGE_SIZE.
If PAGE_SIZE is not defined, it is either using hard coded default,
or getting the system value from the UNIX-only function sysconf().

Such definitions are replaced with the generic function
rte_mem_page_size() defined for each supported OS.

Removing PAGE_SIZE definitions will fix dlb drivers for musl libc,
because #ifdef checks were missing, causing redefinition errors.
