Subject: [PATCH v3 5/5] misc: fastrpc: revert max init file size back to 2MB

From: Jorge Ramirez-Ortiz <jorge.ramirez-ortiz@...aro.org>

With the integration of the mmap/unmap functionality, it is no longer
necessary to allow large memory allocations upfront since they can be
handled during runtime.

Tested on QCS404 with CDSP Neural Processing test suite.
