soc: qcom: hab: increase OUT_LARGE_BUF_SIZE from 50k to 64k

Browse source 
The hab team recommends that the maximum message size that the
hab client can send is 64k. We increase the size of
OUT_LARGE_BUF_SIZE to 64K so that the memory pool can cover
all messages of the recommended size.

In non-stress scenarios, this helps to avoid jitter in the
performance of sending messages due to memory requests.

This change does not result in a large amount of additional
reserved memory, because OUT_LARGE_BUF_NUM is 10, and each
pchan group will only reserves (64k- 50k) * 10 = 140k more memory.
