rpmsg: use less buffers when vrings are small

2014-11-26T16:24:36Z

Adjust the number of rpmsg buffers to rely on the size of the vring, instead of using the hard coded value of 512 (256 per direction). This is needed when small vrings are being used, where 256 buffers are too much to fit in a vring. While considering the vring size, keep using the 512 hard coded value as an upper limit to avoid wacky resource tables consuming unreasonable amount of memory. NOTE: The number of buffers is already assumed to be symmetrical in each direction, and that logic is unchanged.
