[PATCH v2] ASoC: ti: rx51: remove stale reference to machine_is_nokia_rx51()

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

The rx51 driver relies on the machine_is_nokia_rx51() macro, which was
used with the legacy board file dropped in commit 9b7141d01a76 ("ARM:
OMAP2+: Drop legacy board file for n900"). The use of this macro
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. Drop this unused code.

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