Subject: [PATCH] Fix wt_200k_G.c "initializer element is not constant" error
 with GCC < 8.1

Building with GCC < 8.1 would give the following error:

arm-wt-22k/lib_src/wt_200k_G.c:114:5: error: initializer element is not constant
     0x00200000 | sampleRate,
     ^~~~~~~~~~
arm-wt-22k/lib_src/wt_200k_G.c:114:5: note: (near initialization for 'easSoundLib.libAttr')

See also:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69960#c18

Using an 'enum' for the 'sampleRate' value is enough for older GCC releases.
