Add libretech PC platform support. This platform comes in 2 variants, one with the s905d and the other s912.
The corresponding DT have been applied and should be merged during the next merge window [0]
While working on these boards, I've found a problem related the mmc clock. In some cases, the ROM code will leave the mmc clocks in such a weird state that any access to the mmc controller would lock the device.
Making sure the MMC clocks are properly reset and enabled is enough to solve the problem.
