b630d57d0a clk: Add fixed-factor clock driver
This patch adds fixed-factor clock driver which derives clock
rate by dividing (div) and multiplying (mult) fixed factors
to a parent clock.

ecc7973d1c sandbox: sound: Silence sound for testing
When testing the sound system we don't need the hear the beeps. The
testing works by checking the data that would be emitted. Add a

2850266965 sound: Add uclass operations for beeping
Some audio codecs such as Intel HDA do not need to use digital data to
play sounds, but instead have a way to emit beeps. Add this interface as
an option. If the beep interface is not supported, then the sound uclass
falls back to the I2S interface.

27028f186d sandbox: Boot in U-Boot through the standard call
Most architectures use jump_to_image_no_args() to jump from SPL to U-Boot.
At present sandbox is special in that it jumps in its
spl_board_load_image() call. This is not strictly correct, and means that
sandbox misses out some parts of board_init_r(), just as calling
bloblist_finish(), for example.

implement jump_to_image_no_args() to actually jump to it.
