This patch creates tegra_spi_soc_data structure to maintain and implement SPI HW feature differences between different Tegra chips and also creates a separate compatible string for T124/T210. Tegra210 and later has a separate interrupt mask register SPI_INTR_MASK for enabling or disabling interrupts while Tegra124 and prior uses interrupt enable bits in SPI_DMA_CTL register. This patch creates flag has_intr_mask_reg in tegra_spi_soc_data to identify this and implements accordingly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
