ARM: stm32mp: depend on ARCH_STM32MP for SoC drivers ...

The i2c, MCI and reset controller peripherals are STM32-specific.
There is no reason to ask uses on oldconfig about it, thus make them
depend on ARCH_STM32MP || COMPILE_TEST.

reset: add reset controller driver for STM32 RCC ...

On the STM32MP, reset of the I2C, SPI and USB IPs occurs over the RCC.
This driver adds support for the controller, so it may be reused by
other drivers.

Linux commit 26fce05 was squashed
here as well:

  reset: imx7: Fix always writing bits as 0

  Right now the only user of reset-imx7 is pci-imx6 and the
  reset_control_assert and deassert calls on pciephy_reset don't toggle
  the PCIEPHY_BTN and PCIEPHY_G_RST bits as expected. Fix this by writing
  1 or 0 respectively.

  The reference manual is not very clear regarding SRC_PCIEPHY_RCR but for
  other registers like MIPIPHY and HSICPHY the bits are explicitly
  documented as "1 means assert, 0 means deassert".

  The values are still reversed for IMX7_RESET_PCIE_CTRL_APPS_EN.
