[Thomas Monjalon]

PAGE_SIZE is already defined in musl libc:

drivers/net/dpaa2/dpaa2_recycle.c:35: error: "PAGE_SIZE" redefined
/usr/include/limits.h:97: note:
   this is the location of the previous definition
   97 | #define PAGE_SIZE PAGESIZE

Fixes: f023d059769f ("net/dpaa2: support recycle loopback port")
