mb/system76/rpl: Allow 5600 MT/s memory for RPL-HX

System76 only sells units with memory speeds up to 5200 MT/s, but the
i9-13900HX supports up to 5600 MT/s memory.

Tested by running memtest and checking dmidecode reports 5600 MT/s when
using 2x16 GB 5600 MT/s Crucial SODIMMs (CT2K16G56C46S5) on addw3,
bonw15, serw13.
