Subject: [PATCH] staging: iio: meter: enclose Macros with complex values in parentheses

enclose Macros with complex values in parentheses is especially useful
in making macro definitions “safe” (so that they
evaluate each operand exactly once).

this error reported by chechpatch.pl

"ERROR: Macros with complex values should be enclosed in parentheses"

for ADE7854_SPI_SLOW, ADE7854_SPI_BURST and ADE7854_SPI_FAST
macros and this error fixed by enclose these macros in parentheses.
