commit 6bce5efd ("ARM: davinci: remove unused davinci-i2s pdata")
removed all instances of davinci-i2s pdata. However, on DM365 EVM,
the same platform data is passed to the voicecodec present on that
device.

This causes build breakage when voicecodec support is enabled:

arch/arm/mach-davinci/board-dm365-evm.c:764:17: error: 'dm365_evm_snd_data' undeclared (first use in this function)

voicecodec driver does not use the platform data as well, and
it is safe to remove it.

This string is used by dump_stack and as we now support
more SoC's than just STiH415/6 it is misleading to have
the current string in the stack trace.

This patch updates it to be more generic for the STi
family of SoCs.

So instead of looking like this

it now looks like this:
