[PATCH 1/2] hw/dma: sifive_pdma: Improve code readability for "!!foo & bar"

[Bin Meng]

GCC seems to be strict about processing pattern like "!!for & bar".
When 'bar' is not 0 or 1, it complains with -Werror=parentheses:

  suggest parentheses around operand of ‘!’ or change ‘&’ to ‘&&’ or ‘!’ to ‘~’ 
[-Werror=parentheses]

Add a () around "foo && bar", which also improves code readability.
