Subject: clk: bcm: rpi: Add support for VEC clock
Git-commit: 1777cb60f7df80d9b4ca3385eca1d2c0bed61cb6
Patch-mainline: v6.0 or v6.0-rc8 (next release)
References: bsc#1196632

Platform driver clk-bcm2835 gets an inaccurate clock for VEC (107MHz).
Export VEC clock trough clk-raspberrypi which uses the right PLL to
get an accurate 108MHz.
