[PATCH 09/14] ARM: OMAP2+: Don't configure of chip-select options in gpmc_cs_configure()

[Jon Hunter <jon-hunter@xxxxxx>]

With the addition of the gpmc_cs_program_settings(), we no longer need
or use gpmc_cs_configure() to configure some of the GPMC chip-select
options. So rename the function to gpmc_configure() and remove code that
modifies options in the CONFIG1 register.
