platform/x86: msi-ec: Fix the build

Browse Source 
The msi-ec driver fails to build for me (gcc 7.5):

  CC [M]  drivers/platform/x86/msi-ec.o
drivers/platform/x86/msi-ec.c:72:6: error: initializer element is not constant
    { SM_ECO_NAME,     0xc2 },
      ^~~~~~~~~~~
drivers/platform/x86/msi-ec.c:72:6: note: (near initialization for ‘CONF0.shift_mode.modes[0].name’)
drivers/platform/x86/msi-ec.c:73:6: error: initializer element is not constant
    { SM_COMFORT_NAME, 0xc1 },
      ^~~~~~~~~~~~~~~
drivers/platform/x86/msi-ec.c:73:6: note: (near initialization for ‘CONF0.shift_mode.modes[1].name’)
drivers/platform/x86/msi-ec.c:74:6: error: initializer element is not constant
    { SM_SPORT_NAME,   0xc0 },
      ^~~~~~~~~~~~~
drivers/platform/x86/msi-ec.c:74:6: note: (near initialization for ‘CONF0.shift_mode.modes[2].name’)
(...)

Don't try to be smart, just use defines for the constant strings. The
compiler will recognize it's the same string and will store it only
once in the data section anyway.
