The AXP803 has been around for about a decade now, but so far we didn't
need SPL support, since the DRAM rail was wired up correctly at reset.

Now some boards using the A133 SoC use the (compatible) AXP707 with DDR4
memory, which requires the SPL to set the required 1.1V voltage manually.

Add the descriptions for the DC/DC regulators of the AXP803, and enable
that when CONFIG_AXP803_POWER is enabled.

Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.

Update the comment in bootstage to refer to this symbol, instead of
SPL_

The generic AXP SPL driver implementation can cover all regulators we
need for the AXP305.

Add the descriptions for four of the six DC/DC regulators of the AXP305,
and enable that when CONFIG_AXP305_POWER is enabled. We won't need DCDC2
and DCDC3, but by using the position in the array for the index we keep
the code cleaner.
Also remove the old driver, and switch the Makefile to include the new,
generic driver.

The generic AXP SPL driver implementation can cover all regulators we
need for the AXP313.

Add the descriptions for the three DC/DC regulators of the AXP313, and
enable that when CONFIG_AXP313_POWER is enabled. Also remove the old
driver, and switch the Makefile to include the new, generic version.

On boards using the AXP717 PMIC, the DRAM rail is often not setup
correctly at reset time, so we have to program the PMIC very early in
the SPL, before running the DRAM initialisation.

Using the new generic AXP SPL driver, add the Kconfig options and
platform bits needed to support an AXP717 PMIC chip in I2C mode.
This allows to set up the correct voltage for the DRAM chips and the
CPU cores.

The axp<xxx>.c drivers are only used for the SPL, for U-Boot proper we
have a separate, DM compliant driver.
Mask the build instructions with CONFIG_SPL_BUILD, to avoid them being
build for U-Boot proper as well.

The AXP221 driver defines axp_get_sid(), which is used in the U-Boot
proper cpuinfo() code, and some old LCD code directly calls axp_set_eldo(),
so we keep that driver outside the new guards. This will be fixed properly
later.

On boards using the AXP313 PMIC, the DRAM rail is often not setup
correctly at reset time, so we have to program the PMIC very early in
the SPL, before running the DRAM initialisation.

Add a simple AXP313 PMIC driver that knows about DCDC2(CPU) and
DCDC3(DRAM), so that we can bump up the voltage before the DRAM init.
