ARM: OMAP: omap2/gpmc updates
GPMC updates:
- bugfixes: wrong/missing flags, omitted write, wrong test
- don't map memory segments starting at zero
- improve debug messaging
- export gpmc_get_fclk_perio]d() since it's needed to calc timings
- expect gpmc_cs_set_timings() caller to have initialized sync vs async
Note that this API is glitchy; likely the best fix would be to add
a member to "struct gpmc_timings" to hold GPMC_CONFIG1, since that
holds one key aspect of the GPMC timings (the gpmc_fclk divisor,
and sync vs. async == whether that divisor matters).
