Makefile: Update Flags

* Originally I had issues with graphite flags building the whole kernel.  Now they work so I'm going to move them back to build everything.  I also am adding -DNDEBUG flag because it makes things a tad bit smoother.

msm: krait-regulator: handle efuse differences

Scaling factor version is valid for
- 8974 based devices when the version bits read 1
- 8974pro based devices when the version bits read 1 or 2
- 8084 based devices when the version bits read 0
- 8092 based devices when the version bits read 0

Moreover the three bit scaling factor data for
- 8974 based devices starts at bit 16
- 8974pro based devices starts at bit 16
- 8084 based devices starts at bit 14
- 8092 based devices starts at bit 14

Update the code to handle these differences.

msm: krait-regulator: fix unnecessary calls to switch to LDO

When asked to set a LDO voltage the driver rounds it up to
the nearest step value. However, when checking if the requested voltage
is already set it doesn't account for the rounding up.

Fix this by rounding up the requested value, which avoids
unnecessary calls to set the LDO voltage and switch to LDO.
