The rockchip spi would stop driving pins when runtime suspended, which might break slave's xfer(for example cros_ec). Since we have pullups on those pins, we only need to care about this when the CS asserted. So let's keep the spi alive when chip select is asserted. Also use pm_runtime_put instead of pm_runtime_put_sync.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
