clk: sunxi: add PIO bus gate clocks

The introduction of the DM pinctrl driver made its probe function enable
all clocks enumerated in the DT. This includes the "CLK_BUS_PIO" (and
variations) gate clock. Also CLK_PLL_PERIPH0 is used by the R_CCU device.
So far we didn't describe those clocks in our clock driver.
As we enable them already in the SPL, the devices happen to work, but
the clock driver still complains about not finding those clocks:
=========
sunxi_set_gate: (CLK#58) unhandled
=========

Add the one-liners that are needed to announce the gate bit for those
clocks, to silence that message on the console.

SPI peripherals. While we could work around this in the SPL by
hardcoding the required information, this left U-Boot proper without SD

SPI, plus benefit from some fixes.

Patrice Chotard [Fri, 22 Apr 2022 07:38:31 +0000 (09:38 +0200)]
gpio: stm32_gpio: Rework GPIO hole management

On some STM32 SoC's package, GPIO bank may have hole in their GPIO bank
Example:
  If GPIO bank have 16 GPIO pins [0-15].
  In particular SoC's package case, some GPIO bank can have less GPIO pins:
    - [0-10] => 11 pins;
    - [2-7] => 6 pins.

Commit dbf928dd2634 ("gpio: stm32f7: Add gpio bank holes management")
proposed a first implementation by not counting GPIO "inside" hole. GPIO
are not displaying correctly using gpio or pinmux command when GPIO holes
are located at the beginning of GPIO bank.

To simplify, consider that all GPIO have 16 GPIO and use the gpio_ranges
struct to indicate if a GPIO is mapped or not. GPIO uclass offers several
GPIO functions ("input", "output", "unused", "unknown" and "func"), use
"unknown" GPIO function to indicate that a GPIO is not mapped.

stm32_offset_to_index() is no more needed and removed.

This must be reflected using the "gpio" command to indicate to user
that a particular GPIO is not mapped (marked as "unknown") as shown below:

Example for a 16 pins GPIO bank with the [2-7] mapping (only 6 pins
mapped):
GPIOI0          : unknown
GPIOI1          : unknown
GPIOI2          : analog
GPIOI3          : analog
GPIOI4          : alt function 0 push-pull pull-down
GPIOI5          : alt function 0 push-pull pull-down
GPIOI6          : alt function 0 push-pull pull-down
GPIOI7          : analog
GPIOI8          : unknown
GPIOI9          : unknown
GPIOI10         : unknown
GPIOI11         : unknown
GPIOI12         : unknown

misc: atsha204a: Add support for atsha204 chip

atsha204 chip is predecessor of atsha204a chip. Current U-Boot driver
atsha204a-i2c.c can use both atsha204 and atsha204a chips because it does
not call specific functions to just one of these chips.

So just add compatible string for atsha204.
