reset: sti: simplify driver's config and build

With commit 64933513e461 ("reset: sti: Remove STiH415/6 reset support"),
there is only one sti reset driver left and there no need to define a
dedicated config STI_RESET_SYSCFG, which is selected by the config for the
STiH407 reset driver.

Simply add reset-syscfg.c to the build for the STiH407 reset driver.

reset: stih407: Add softreset, powerdown and picophy controllers

This patch adds softreset, powerdown and picophy reset controllers for
the STiH407 SoC.

With this patch three new devices are registered: -
1. st,stih407-powerdown
2. st,stih407-softreset
3. st,stih407-picophyreset

All three devices use system configuration registers mapped via regmap to
perform the reset or powerdown. The powerdown controller also has
an acknowledgement.

A separate picophy reset controller manages the different reset channels within
the picophy, which have a different polarity to the other system softresets.
Managing these different picophy softreset channels is necessary to correctly
handle resuming from suspend when USB2 devices are plugged into the USB3 port.

This patch adds a reset controller platform driver for the STiH416
SoC. This initial version provides a compatible driver for the
"st,stih416-powerdown" device, which registers a system configuration
register based reset controller that controls the powerdown state of
hardware such as the on-chip USB host controllers.

drivers: reset: STi SoC system configuration reset controller support

This patch adds a reset controller implementation for STMicroelectronics
STi family SoCs; it allows a group of related reset like controls found
in multiple system configuration registers to be represented by a single
controller device. System configuration registers are accessed through
the regmap framework and the mfd/syscon driver.

The implementation optionally supports waiting for the reset action to
be acknowledged in a separate status register and supports both
active high and active low reset lines. These properties are common across
all the reset channels in a specific reset controller instance, hence
all channels in a paritcular controller are expected to behave in the
same way.
