kbuild: Fix gcc -x syntax

commit b1e0d8b70fa31821ebca3965f2ef8619d7c5e316 upstream.

The correct syntax for gcc -x is "gcc -x assembler", not
"gcc -xassembler". Even though the latter happens to work, the former
is what is documented in the manual page and thus what gcc wrappers
such as icecream do expect.

This isn't a cosmetic change. The missing space prevents icecream from
recognizing compilation tasks it can't handle, leading to silent kernel
miscompilations.

Besides me, credits go to Michael Matz and Dirk Mueller for
investigating the miscompilation issue and tracking it down to this
incorrect -x parameter syntax.

msm_fb: display: add one more pipe_commit delay before free ion buffer

It is possible that two consective pipe_commits happen within
same vsync period.  This will cause iommu page fault due to an ion buffer
that is being fetched by mdp's pipe is freed. It needs one pipe_commit
delay to free ion buffer to prevent iommu page from happening. Therefore
an extra free stage is needed to empty ion buffer free list.
Also, ION_IOMMU_UNMAP_DELAYED flag is not necessary at mapping of an
ion buffer since one pipe_commit delay had been added.

Previously the WFD driver was reponsible for signalling the

signalling is better purposed when done from MDP driver.
