Subject: [PATCH v2 0/4] Add missing bug fixes

Add missing bug fixes in memory areas. This patch series carries
following fixes:
- Add proper checks to fastrpc_buf_free to avoid potential issues.

  - Store the spinlock pointer in the struct fastrpc_buf instead
  - Allocate entire reserved memory to audio PD through remote heap
