h1r9: use single SSP configuration for MAX283x

Browse Source 
During r9 hardware development it was thought that the MAX2839 would use
a different GPIO pin for chip select, but it ended up being the same pin
as is used for MAX2837 on other hardware revisions.

This takes the MAX283x abstraction a bit further and fixes a bug with
hackrf_debug -m.
