Subject: arch/arm/plat-omap/iovmm.c: fix end address of vm area comparation in alloc_iovm_area
From: Fernando Guzman Lugo <x0095840@ti.com>

End address of the vm area is .start + bytes -1., not start + byte.  This
patch fixes that issue by doing an inclusive comparison with
tmp->da_start.  This issue was preventing allocate an area of size exactly
the same than the free area.  I did no change the value of da_end of each
vm area because it is used to get area size in several places.
