Changed to define ambiq spi/i2c dma mode as a binding property
instead of kconfig macros, making it more flexible for different
spi/i2c instances.

The x_nucleo_gfx01m2 is an evaluation shield sold by
STMicroelectronics. It features a MIPI DBI SPI serial TFT LCD display
and a SPI NOR Flash for graphical assets storage. A button joystick
can be used to control the GUI.

Most SPI NOR flash devices support a "fast read" command which uses
dummy bits between the address and the start of the data transfer. In
many cases, the maximum SPI clock speed of the device is lower for the
regular read command due to the limited time between the address and
data phases, so using the fast read command will remove this restriction
and allow for faster transfers.
Add a device tree flag to indicate that fast reads should be used for
the device.

Some Micron (and possibly other) SPI NOR devices implement a flag status
register which provides more information on the success/failure of erase
and program operations. In addition to better error checking, some of
these devices actually don't function properly if the flag status
register is not read after a program operation (subsequent reads will
only return 0xFF bytes).
Add a device tree parameter to indicate that the flag status register is
supported. When specified, the flag status register will be used for
ready/error checks rather than the standard status register.

This driver was providing SPI buffers for both TX and RX on the data
payload portion of read transfers, even though the TX buffer is not
meaningful in these cases. As well as being less efficient, this also
caused likely uninitialized data to be transferred to the device, which
is possibly problematic.
Update to not include the TX buffer for the read data payload SPI
transfer, so that the SPI driver can generate dummy TX data internally.

Add the 4Bytes program mode to the stm32_ospi driver
to enter 4-Byte Address Mode (SPI_NOR_CMD_4BA) when flash is supporting it.
This is given by the JESD216 SFDP table.
Based on the stm32 qspi driver.

The original Wi-Fi certificates are from WFA. Now replace them with
certificates that generated by myself. These certificates use

The value read from unwritten areas of Renesas RAxxx SoCs data
flash is undefined. To prevent reading unwritten areas a
blank check command is performed first. If the area is blank, we
return dummy data so it behaves the same as other flash devices.

Use the same logic as the top-level Zephyr CMakeLists.txt does to
find the linker script option by using the first one of these
which is set:
1. Global TOPT property
2. Compiler's linker_script property
3. -Wl,-T
This avoids toolchains which insert a default linker script
when none is provided on the command line using the -T option.
