riscv: dts: thead: Add edge-triggered option for wireless nodes

After extensive testing it seems like the wireless chips used on the
TH1520 SoC - aic8800 and rtk connected to PCA9557 I/O expander are
connected so in an unstable way. There is a need to flip GPIO values
0->1 with some delay in order for the chips to start predictably.

net: rfkill: rfkill-gpio: Add workaround for faulty interconnect design

Vendor provided custom rfkill drivers seems to restrict operation of
rfkill to only enable the Wi-Fi/Bluetooth at the start. The flipping
on/off is restricted. Additionally they include a lot of delays when
accessing GPIO controller pcal6408ahk_c. This seems to indicate some
instability in the hardware.

So I spent some more time trying to analyze this, and here's what I
found:
1) The delays are not really needed. The GPIO controller and i2c bus
   seems to work correctly as designed. So I don't think any
   modifications in the GPIO/i2c drivers are appropriate.
2) The thing that is really needed is the state change on the GPIO line
   connected to the wireless chip i.e the value on the GPIO is already 1
   on the boot, but it needs to go from 0->1 for Wi-Fi chip to get up
   properly.

In the new implementation work around this by introducing new option
'edge-triggered'. This allows for the the state change on GPIO 0->1,
which seems to be required by the wireless chip to start working
correctly.

There is still msleep() required between flipping GPIO values, it seems
like there is no way around this.

Nevertheless in the new implementation it should be possible to turn the
power on/off to Wi-Fi and Bluetooth programatically, through this
crashed the driver in my testing.

Here's what happens: the __mmc_start_request function is called with
opcode 5. Since the power to the Wi-Fi card, which resides on this SDIO
bus, is initially off after the reset, an interrupt SDHCI_INT_TIMEOUT is
triggered. Immediately after that, a second interrupt SDHCI_INT_RESPONSE
is triggered. Depending on the exact timing, these conditions can
trigger the following race problem:

1) The sdhci_cmd_irq top half handles the command as an error. It sets
   host->cmd to NULL and host->pending_reset to true.
2) The sdhci_thread_irq bottom half is scheduled next and executes faster
   than the second interrupt handler for SDHCI_INT_RESPONSE. It clears
   host->pending_reset before the SDHCI_INT_RESPONSE handler runs.
3) The pending interrupt SDHCI_INT_RESPONSE handler gets called, triggering
   a code path that prints: "mmc2: Got command interrupt 0x00000001 even
   though no command operation was in progress."

To solve this issue, we need to clear pending interrupts when resetting
host->pending_reset. This ensures that after sdhci_threaded_irq restores
interrupts, there are no pending stale interrupts.

btrfs: fix kvcalloc() arguments order in btrfs_ioctl_send()

When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed the following warning:

fs/btrfs/send.c: In function 'btrfs_ioctl_send':

Since 'n' and 'size' arguments of 'kvcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the result
and so this is not a bug. But it's still worth to fix it.

riscv: dts: thead: Add device tree for hdmi port and dependent nodes

Hdmi port device tree node requires a lot of extra dependencies.
hdmi_tx node depends on disp1_out, which depends on enc1_in.

Additionally the main node for display subsystem, called
display-subsystem depends on dpu_disp0 and dpu_disp1.

There are additional dependencies on dsi0 nodes for lcd0_backlight,
pcal6408ahk_d, soc_vdd18_lcd0_en_reg, soc_vdd33_lcd0_en_reg, which
in turn brings a lot of pinctrl and i2c nodes.

Add all the required nodes for the drm subsystem to load correctly.
