This fixes a crash at boot on 64-bit risc-v systems which need to store
64-bit registers to the stack aligned to 8 byte boundary.
Specifically, this uses 8 bytes to store ra and s0 on rv32 and 16 bytes on
rv64, and does the register stores and loads properly aligned acc. to the
register size.

This commit includes a change to the esp_txint function in the arch/risc-v/src/common/espressif/esp_usbserial.c file. The change primarily involves removing an optimization workaround and adding a call to flush the transmit FIFO.
After this change the usbserial config is able to work using all optimization levels.
Changes in esp_txint function:
Removed the __attribute__((optimize("O0"))) workaround.
Added a call to usb_serial_jtag_ll_txfifo_flush() at the beginning of the function.

It is now possible to configure SPI delays for st7789 controller if
CONFIG_SPI_DELAY_CONTROL is set. Default values for SPI peripheral
may be too long or too short, therefore the display controller set
its own values as required. The default values in configuration
are taken from the reference manual, but it is possible they may
require tuning for different revisions or temperatures for
example.

This commit improves the configuration of complementary PWM mode for
Tiva C-Series microcontrollers by moving the complementary flag
definition directly into each channel structure.
Changes made:
- Renamed 'complementary_generation' to 'complementary' for clarity.
- Moved complementary mode configuration into the static PWM
channel structures.
- Replaced runtime conditional checks with compile-time configuration
using '#ifdef CONFIG_TIVA_PWM_COMPLEMENTARY_Gx'.
- Improved readability and maintainability of the PWM driver.
These modifications ensure a more efficient initialization process,
reduce runtime conditionals, and align better with NuttX coding practices.

This ioctl clears the active fault inputs. Some faults can be latched
(still active even if the source is not active anymore), so they have
to be cleared from the software. The argument is a pointer to unsigned
long bitmask variable. This bitmask specifies which faults are to be
cleared.
The ioctl also can fetch the faults active prior to the clear. These
faults are saved to the argument specifying which faults are to be
cleared. Therefore passing zero bitmask means the driver will only return
active faults and clear none. Passing NULL pointer means the driver
will clear all active and return none.
The implementation of this ioctl is per driver.

`boot_stage_puts` used by early asm calls arm64_lowputc() for each
character in a loop. During that loop it uses x1 as the pointer to
the next character to be printed. However, x1 is clobbered by
arm64_lowputc(), resulting in undefined behaviour (only the first
character of the string is guaranteed to be printed).
Fix this by using x19 instead.
