staging: comedi: s626: specify bitshift for encoder A clock source
When setting the clock source for one of the 'A' encoders to operate in
"counter" mode in `s626_set_mode_a()`, bitshift the clock source value by
`S626_CRABIT_CLKSRC_A` for consistency with the other modes. This has
no effect on the value since `S626_CRABIT_CLKSRC_A` is 0.
