ARM: footbridge: remove addin mode
This does not appear to have been used in many years, we can
kill off some of the uglier code.
Among other things, it avoids a randconfig issue when both modes
are disabled:
arch/arm/mach-footbridge/common.c:149:24: error: 'ebsa285_host_io_desc' defined but not used [-Werror=unused-variable]
149 | static struct map_desc ebsa285_host_io_desc[] __initdata = {
| ^~~~~~~~~~~~~~~~~~~~
arch/arm/mach-footbridge/common.c:136:24: error: 'fb_common_io_desc' defined but not used [-Werror=unused-variable]
136 | static struct map_desc fb_common_io_desc[] __initdata = {
| ^~~~~~~~~~~~~~~~~
The recently added phys_to_dma() functions are now trivial and
could probably be removed again as a follow-up, if anyone knows
how.
