STM32 DT fixes for v5.4, round 2

Highlights:
-----------

Fixes for STM32MP157:
 -Fix CAN RAM mapping
 -Change stmfx pinctrl definition for joystick and camera. Due to
 stmfx pinctrl fix done in v5.4-rc cycle, camera and joystick were no
 longer functional.

The MMA8451 interrupt triggers as low level, so the GPIO6_IO31 pin
needs to activate its pull up, otherwise it will stay always at low level
generating multiple interrupts.

The current device tree does not configure the IOMUX for this pin, so
it uses whathever comes configured from the bootloader.

The IOMUXC_SW_PAD_CTL_PAD_EIM_BCLK register value comes as 0x8000 from
the bootloader, which has PKE bit cleared, hence disabling the
pull-up.

Instead of relying on a previous configuration from the bootloader,
configure the GPIO6_IO31 pin with pull-up enabled in order to fix
this problem.

and dra7 causing a device reset.

Turns out I made several mistakes implementing the watchdog quirk handling:

1. We must do both writes to spr register

2. We must also call the reset quirk on disable

3. On am3 and am4 we need to also set swsup quirk flag

wasn't quite right.  Looking at /sys/kernel/debug/clk/clk_summary on

266,666,667 Hz achieved by dividing the 800 MHz PLL by 3.

Looking at history, it seems that even Sean's first patch [1] had this
funny clock rate.  I'm not sure where it came from since the commit
message specifically mentioned 26666 kHz and the Chrome OS tree [2]
can be seen to request 266667 kHz.

In any case, let's fix it up.  This together with my patch [3] to do
the proper rounding when setting the clock rate makes the VOP clock
more proper as seen in /sys/kernel/debug/clk/clk_summary.

And with commit e6818d29ea15 ("gpio: gpio-omap: configure edge detection

Fixes for omaps for v5.4-rc cycle

Here are fixes for omaps to deal with few regressions, and to fix
more boot time errors and warnings:

- The recent ti-sysc interconnect target module driver changes had
  incorrect clock bits for both clocks and dts that cause warnings

- For omap3-gta04, gpio changes caused the LCD to break a while back,
  and after discussing things the right fix is to set spi-cs-high

- Recent omapdrm changes to use generic panels caused tfp410 to be
  disabled as we now must enable the generic support for it in
  defconfig

- Recent omapdrm and backlight changes also finally made droid4 LCD
  to work, so let's enable it in the defconfig it can be used out
  of the box. This is not strictly a fix, but we still also have the
  older CONFIG_MFD_TI_LMU options available so this cuts down the
  confusion for trying to guess which display and which backlight
  is needed

- Recent ti-sysc interconnect target module changes need the gpio
  module disabled on some boards, but this now needs to happen at
  the module level, not at the gpio driver level

- Recent changes to probe system timers with ti-sysc caused warnings
  about mismatch in syconfig registers, so let's configure the option
  for RESET_STATUS as available in the TRMs

- Recent changes to probe LCDC with ti-sysc caused warnings about
  mismatch in sysconfig registers, so let's configure the missing
  idlemodes for both platform data and dts as documented in TRMs

- Since we moved mach-omap2 to probe with device tree, we've been
  getting voltage controller warnings. Turns out this code is no
  longer needed, so let's just remove omap2_set_init_voltage() to
  get rid of the pointless warnings
