kingst-la2016: add support for kingst la1016

The Kingst LA2016 and LA1016 use the same hardware, just the coding
of authentication IC U10 is different. U10 limits the LA1016 to
using an FPGA bitstream that samples at a maximum of 100MHz. Other
than that, the devices operate identically and the driver just needs
to select the correct bitstream and limit the maximum sample rate
appropriately. This commit adds support for the existing two hardware
revisions of LA1016, which require different bitstreams.
