it's a bit confusing. PREVENT_FIRMWARE_BUILD=y is the 'weaker' option - 
a driver might still be operational (with its default firmware), even if 
no firmware is built. STANDALONE=y is the stronger option - if a driver 
depends on that it means that the driver cannot be built (and used) at 
all without a firmware file. To be on the safe side users who have no 
firmware needs should set both options. (and that's the default as well)
