dm: serial: set flag GD_FLG_SERIAL_READY if CONFIG_ROCKCHIP_VIDCONSOLE is enabled

For RK platforms, the CONFIG_DEBUG_UART_ALWAYS is enabled by
default, so the GD_FLG_SERIAL_READY will not be set in serial_init()
of drivers/serial/serial_uclass.c, which makes stdout support only
"serial".

If GD_FLG_SERIAL_READY is not set, the console will only use
the function printch() to show the logs. The related codes in
common/console.c are:

void putc(const char c)
......
/* if we don't have a console yet, use the debug UART */
if (!gd || !(gd->flags & GD_FLG_SERIAL_READY)) {
printch(c);
return;
}
......
}

In order to show logs on srcreen via the video console, we set
the flag GD_FLG_SERIAL_READY in serial_init() if the config
CONFIG_ROCKCHIP_VIDCONSOLE is enabled.

With the current implementation dev is equivalent to !ret. It is
redundant to check both, ret check can be replaced with dev check, and
ret check inside the iteration is dead code.

1. We bind all serial nodes including UART debug node from kernel dtb.
2. On some rockchip platforms, UART debug and SDMMC pin are multiplex.
Without this, iomux is switched from SDMMC => UART debug at this time.

dm: serial: bind stdout device anyway

If the console is not marked to be bound, bind it anyway.

This makes serial node in U-Boot dtb no need to be enabled
and bound into dm tree since they are not sured to be the
stdout for pre-loader serial.

This avoids the mix of kernel and U-Boot serial node under
serial uclass list, otherwise serial device bound from U-Boot
dtb always have the higher priority.

serial: serial-uclass: Add generic serial RX buffer support

Pasting longer lines into the U-Boot console prompt sometimes leads to
characters missing. One problem here is the small 16-byte FIFO of the
legacy NS16550 UART, e.g. on x86 platforms.

This patch now introduces a Kconfig option to enable RX buffer support
for all DM based serial drivers. With this option enabled, I was
able paste really long lines into the U-Boot console, without any
characters missing.

Some platforms have very limited SRAM to run SPL code, so there may

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,

space independently.
