[Cbe-oss-dev] [PATCH 01/23]MARS/base: usable spe count

[Yuji Mano]

From: Kazunori Asayama <asayama at sm.sony.co.jp>

Use number of usable SPEs instead of number of physical SPEs

This patch modifies the mars_mpu_max() function so it uses # of usable
SPEs instead of # of physical SPEs in order to avoid allocating system
SPEs or NOSCHED SPEs to MARS.
