stm32mp-t1000: Fix clock configuration

See merge request !3

Fix some overclocking for SAI interfaces. Also some clock
configurations are improved. Changed clocks are:

- SAI1 to SAI4
- UART1
- UART78
- SDMMC3

Integrate changes of v2.4-stm32mp-r2.1 version from ST

See merge request !2

When SSP is built using USB mode, all UART nodes are
disabled except console. Aliases must be also removed.

Gateable clocks, listed in stm32mp1_clk_gate[] table, get resumed in
stm32mp1_clock_resume() function, when returning from Standby state.
If a clock is always-on, like RTC, it doesn't get a refcount. So the
resume function tries to disable it. Such clocks should then be skipped
in the gate resume loop.
