drivers: Rename `random` to `entropy` This should clear up some of the confusion with random number generators and drivers that obtain entropy from the hardware. Also, many hardware number generators have limited bandwidth, so it's natural for their output to be only used for seeding a random number generator.

menuconfig ENTROPY_GENERATOR
Kconfig: Use a short, consistent style for prompts Consistently use config FOO bool/int/hex/string "Prompt text" instead of config FOO bool/int/hex/string prompt "Prompt text" (...and a bunch of other variations that e.g. swapped the order of the type and the 'prompt', or put other properties between them). The shorthand is fully equivalent to using 'prompt'. It saves lines and avoids tricking people into thinking there is some semantic difference. Most of the grunt work was done by a modified version of https://unix.stackexchange.com/questions/26284/ how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some of the rarer variations had to be converted manually.
