The twl4030-power driver contains two checks for ARM machine IDs via
machine_is_*() macros. The two boards concerned now support only FDT
booting, which does not use machine IDs, and therefore the code should
be updated to check the DT compatible property instead.
The legacy board files for these machines were removed in
commit 1b383f44aabc ("ARM: OMAP2+: Drop board file for 3430sdp") and
commit e92fc4f04a34 ("ARM: OMAP2+: Drop legacy board file for LDP").
The presence of these machine ID checks prevents the removal of machine
IDs no longer used by the kernel from arch/arm/tools/mach-types,
because the machine_is_*() macros are generated from mach-types. To
resolve this issue, use of_machine_is_compatible() instead.

Changes from v1: Fix mistake in commit message and remove Fixes tags -
machine ID checks still work with DT booting if the bootloader passes
the ID

The omap3pandora driver contains a check for the ARM machine ID via the
machine_is_omap3_pandora() macro. The board concerned now supports
only FDT booting, which does not use machine IDs, and therefore the
code should be updated to check the DT compatible property instead. The
legacy board file for this machine was removed in commit 7fcf7e061edd
("ARM: OMAP2+: Remove legacy booting support for Pandora").
The presence of this machine ID check prevents the removal of machine
IDs no longer used by the kernel from arch/arm/tools/mach-types,
because the machine_is_*() macros are generated from mach-types. To
resolve this issue, use of_machine_is_compatible() instead.
