Before I selected the name, I figure out that read_reg_* and write_reg_*
was assigned inside the iio/meter/ade7754-(i2c|spi).c files by function
like ade7754_*_read_reg_* and ade7754_*_write_reg_* .
I considered to use 'value' name for both functions parameters, however,
I noticed that function ade7754_*_write_reg_* adopted the name 'value'
for the last argument and ade7754_*_read_reg_* named the last argument
as 'val'. So, for consistency sake between the header file and the c
code, I decided to use the same parameter name patterns.
