SPI bus clocks can be avoided passing through platform
data as spi driver is getting the bus clock using the
generic clock connection id registered via clkdev.

This patch changes the code setting range of GPIO pins' configuration and
pull state to use the recently introduced s3c_gpio_cfgpin_range().
NOTE: This is for missed things from the previous patch.

Move the S3C64XX specific device and setup files into mach-s3c64xx as
they are unlikely to be used outside of this code.

Move the register and GPIO definition files from plat-s3c64xx into the
machine include direcotry as they are unlikely to be reused outside
mach-s3c64xx.

This move includes removing the empty <mach/regs-clock.h> and replacing
it with the <plat/regs-clock.h> implementation.

The s3c64xx_spi_set_info() sets one of two platform data structures depending
on which controller is being specified. Change to taking a pointer to the
relevant platform data structure and then having one set of code to place
the data into the area being pointed to.

Platform devices for SPI Controller of S3C64XX are defined and exported for
machines to include. Also, controller setup helper functions are defined for
machine code to set runtime configuration of the controller and the bus.
