[uart] Fix line continuation in DV code
The backslash operator doesn't have the intended effect of line
continuation here and inserts whitespace (all spaces from the start of
the line to the of the second/continued line).
Found by Verible lint:
```
../src/lowrisc_dv_uart_env_0.1/uart_env_pkg.sv:78:18: The lines can't be continued with '\', use concatenation operator with braces [Style: forbid-line-continuations] [forbid-line-continuations]
