Soft resetting a STM32 device currently does not reset the USB
connection, which causes a few problems: The endpoints do not respond
anymore, and within zephyr any kind of status information like
CDC_SET_CONTROL_LINE_STATE is also missing as they are not
re-negotiated.
This is fixed by stopping the USB device from zephyr side, right after
initialising the USB device.

The HAS_I2C_DW was to limit Kconfig visibility to only platforms
that utilize the I2C DW IP. The Kconfig for I2C_DW depends on
DT_HAS_SNPS_DESIGNWARE_I2C_ENABLED which will cause the same
visbility limitation to only platforms that have I2C DW devicetree
nodes. Thus we can remove HAS_I2C_DW and its references.

MSIS frequency at boot time can be different from the one we intent to

In order to avoid issues, read MSIS configuration from registers to get
the actual freq rather than the devicetree one which may be not yet
configured (which is the case at startup).

When configuring PLL, we should first make sure we're not running on PLL,
and if running on PLL, first switch to a fixed clock before proceeding
with PLL configuration.
Current code is doing the switch systematically which is not useful as
default startup case is to use MSI as sysclk source.
So add a test before doing this switch.

Unlike stated in 57df225b396e43358aac4cc998ed2e99fdb57780, RM0456.pdf
reference manual mentions about PLL1R that "Only division by 1 and even
division factors are allowed."
Though, in reference manual, there is one issue on PLL1R values
description, which should actually be:
0000000: pll1_r_ck = vco1_ck
0000001: pll1_r_ck = vco1_ck / 2 (default after reset)
0000010: Not allowed
0000011: pll1_r_ck = vco1_ck / 4

AST10x0 series SOCs provide the clock controller through the syscon
hardware block. The current driver supports the clock gating capability
for the hardware IPs embedded in the SOC. Each clock source has a
clock ID that can simply map to a bit in syscon registers CLK_STOP_CTRL0
(group 0) or CLK_STOP_CTRL1 (group 1). There are some clock sources
that don't have associated clock gating control, which are always on,
are grouped to into group 2.

Add the ssd16xx_read_ram() function that can be used to read the raw
contents of the two display RAM in the controller. This function is

contents of the old frame buffer after a partial refresh that
automatically swaps the black/red buffers.

Read operations only work on SPI controllers that support half

This commits refactors implementation of the pwm_set_cycles function
to fix the following issues:
- when a channel was already set with a non-zero pulse width, setting
cycles for another one required specifying a matching period value,
even if that value was to be ignored anyway when the channel was to
be set to constant inactive or active level; due to this limitation,
it was not possible to e.g. use the LED driver API and turn off a LED
while another one (within the same PWM instance) was blinking
- the above limitation also applied when a channel was set with a pulse
width equal to period (duty 100%); even though such channel was not
in fact using the PWM peripheral, other channels within the same PWM
instance were forced to use the same period
- after a PWM generation was started for a channel, it was not possible
to change its pulse width before two PWM periods passed (while it
should be possible to change it after every period); this was caused
by a looping mechanism that was unnecessarily activated in the PWM
peripheral
