Remove 10us delay in cdns_spi_process_fifo() (called from cdns_spi_irq()) to fix data corruption issue on Master side when this driver configured in Slave mode, as Slave is failed to prepare the date on time due to above delay. Add 10us delay before processing the RX FIFO as TX empty doesn't guarantee valid data in RX FIFO.

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.
