can: rcar_canfd: Add max_aflpn variable to struct rcar_canfd_hw_info

Browse Source 
R-Car Gen3 has maximum acceptance filter list page number of 31 whereas on
R-Car Gen4 it is 127. Add max_aflpn variable to struct rcar_canfd_hw_info
in order to support RZ/G3E that has max AFLPN of 63.

While at it, rename the parameter x->page_num in RCANFD_GAFLECTR_AFLPN
macro to make it clear.
