fbtft: Fix the initialization from property algorithm
When converting to device property API the commit 8b2d3aeeb7ec ("fbtft: Make use of device property API") mistakenly placed the reading of the first value inside the loop, that jumps over value after initialization sequence or sleep commands. Move the above mentioned reading outside of the loop to restore correct behaviour. Besides that, we are using pre-increment operation which may lead to out of the boundary access at the end of sequence. Thus, allocate buffer with an additional element at the end to prevent out of the boundary access.

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.
