Charulatha V 1a5d81905a OMAP: devices: Modify McSPI device to adapt to hwmod framework
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.
