Cleans up all base address definitions for omap_mcspi and adapts the device registration and driver to hwmod framework. Changes involves: 1) Removing all base address macro defines. 2) Using omap-device layer to register device and utilizing data from hwmod data file for base address, dma channel number, Irq_number, device attribute(number of chipselect). 3) Appending base address with pdata reg_offset for omap4 boards. For omap4 all regs used in driver deviate with reg_offset_macros defined with an value of 0x100. So pass this offset through pdata and append the same to base address retrieved from hwmod data file and we are not mapping *_HL_* regs which are not used in driver.
