additional minor changes:
* rename PAGE_SIZE register MH_PAGE_SIZE in yamato/22/yamato_genreg.h (although this is an unused debug file so far)
* remove references to stdio files in gsl_debug_pm4.c (will come in handy later)
* mutex, events, sleeps, process id unabstracted
* defines for function types (inline, extern) unabstracted
* defines for debug assert change name (KOS_ASSERT -> DEBUG_ASSERT) and left disabled
* driver now warns, if logging is enabled, that interruptible mutex locks are interrupted (which never happens in reality but it fixes a warning)
* remove fine grained locking "feature" since it's not enabled (and Qualcomm's public driver does not even implement it)
* refine mutex initialization where it's still present - don't try and allocate mutex structures where they're always used, just make them parts of the structure (struct mutex * -> struct mutex)
* whitespace police
apertures instead of PHYS and EMEM1/MMU and EMEM2. Modify setup to utilize all of reserved memory for PHYS
aperture instead of splitting. Now, a 32MB (in platform fixup, mx51_efikamx.c) reserved block is utilized as
the PHYS, or an 8MB chunk is carved out of coherent memory space (DMA allocation) if reservation is disabled.
Normal memory usage for a desktop with browser, office and media player is well over 64MB but the Xorg driver
will evict unused pixmaps where necessary to keep the current performance pixmaps in place.
With MMU enabled, there is no need to reserve memory for GPU
at boot time

If GPU error interrupt detected, related device will be destroyed.
In the destory function, device_idle and mutex_lock may cause sleep,
which may cause kernel crash, so delay the device destroy to the
workqueue to avoid this.

If enabled MMU, there is AXI read/write error on MX508 when run
OpenVG CTS.
Besides, change EMEM1 size to 10MB by default to make gpu driver
work on MX50_ARM2 board with 128MB memory installed.

Remove GSL_MMU_TRANSLATION_ENABLED macro originally used for conditional

When X-accel is enabled, uio driver is used for X server to access
z160 device, so in gsl, we should not operate z160 to avoid conflicts
