* changes:
fix(spi-nand): add Quad Enable management
fix(st-clock): disabling CKPER clock is not functional on stm32mp13
fix(st-uart): skip console flush if UART is disabled
fix(st): flush UART at the end of uart_read()
fix(stm32mp1): use the BSEC nodes compatible for stm32mp13
fix(stm32mp13-fdts): correct the BSEC nodes compatible
fix(stm32mp1-fdts): move /omit-if-no-ref/ to overlay files
fix(stm32mp1): properly check PSCI functions return
The mask used to configure the CKPER MUX was wrong and unnecessary.

Check the USART_CR1_UE bit and if it is 0, the UART is not enabled,
or not clocked (but the read won't freeze the bus and will return 0).
In this case skip the console flush.

The cpu_macros.S file is loaded with lots of definitions for the cpu_ops
structure. However, since they are defined as .equ directives they are
inaccessible for C code. Convert them to #defines, put them into order,
refactor them for readability, and extract them to a separate file to
make this possible.
This has the benefit of removing some Aarch differences and a lot of
duplicate code.

Returning enum usb_status in an enum usb_action function is wrong as
they have different meanings. However, usb_dwc2_ep0_out_start() and
usb_dwc2_activate_setup() only return USBD_OK so we will never get to

The parameter over_sampling of stm32_uart_init_s is not required
as it can be computed dynamically from clock rate of the serial
device and the requested baudrate.
Oversampling by 8 is allowed only for higher speed
(up to clock_rate / 8) to reduce the maximum receiver tolerance
to clock deviation.
This patch update the driver, the serial init struct and the
only user, the stm32cubeprogrammer over uart support.

For SD-cards, CMD6 is used to switch functions, like setting high speed
mode. As it has another meaning for eMMC, and may not work on standard
capacity SD-cards, it must be checked with MMC_IS_SD_HC flag.
As ACMD6 is also used, and will have the same index, a check on
CMD/ACMD commands is done: a boolean is stored depending on previous
command. It is set to true if CMD55 is issued, for other commands
it is set to false.
