bnxt_en: Reduce maximum ring pages if page size is 64K.
The chip supports 4K/8K/64K page sizes for the rings and we try to
match it to the CPU PAGE_SIZE. The current page size limits for the rings
are based on 4K/8K page size. If the page size is 64K, these limits are
too large. Reduce them appropriately.
