[PATCH v2] ASoC: fsl: eukrea-tlv320: update board checks to use the DT

[Ethan Nelson-Moore <enelsonmoore@gmail.com>]

The eukrea-tlv320 driver contains checks for ARM machine IDs via
machine_is_*() macros. The 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.
Non-DT booting support for these machines was removed in these
commits:
commit f2f55499942a ("ARM: imx: Remove eukrea_mbimxsd35 non-dt support")
commit 3877942b0c7f ("ARM: imx25: Remove eukrea mx25 board files")
commit 7c5deaf77526 ("ARM: i.MX: Remove mach-cpuimx27sd board file")
commit 8da4d6b2f798 ("ARM: mx51: Remove mach-cpuimx51sd board file")

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.
