ASoC: soc.h: Add SOC_ENUM_EXT_ACC() to allow setting access flags 



Add a macro SOC_ENUM_EXT_ACC() to allow the access permission flags
to be set. This is the same as SOC_ENUM_EXT() but with an extra
argument for the access flags.

This will be used by the cs35l56.c driver to create a read-only
volatile enum. It's preferable to avoid custom control macros in codec
drivers. Code maintenance is easier if all control macros are defined
together in soc.h.

This commit only creates this one macro that is actually going to be used.
There's no point cluttering soc.h with unused macros - that just adds a
maintenance burden. People can add equivalents for the other macros if
they need them.
