This relates to graphics which is only active when CONFIG_VIDEO is
enabled. Move it into that directory.

For most boards there is no harm in compiling it always, since it if not
used it will be dropped by the linker. But for the EFI app this is not
the case, so retain use of the BMP Kconfig.

CONFIG_$(SPL_TPL_)SYS_MALLOC_F_LEN is defined as hex. If set to zero
manually, .config contains '0x0' and not '0' as value.

The default value for CONFIG_SPL_SYS_MALLOC_F_LEN should not be set to 0
but to 0x0 if CONFIG_SPL_FRAMEWORK=n to match a manually set value.

USB hubs run in host mode not in gadget mode. Hence, compiling usb_hub.c

The current cread_line() function is very long. It handles the escape
processing inline. The menu command does similar processing but at the
character level, so there is some duplication.

Split the character processing into a new function cli_ch_process() which
processes individual characters and returns the resulting input character,
taking account of escape sequences. It requires the caller to set up and
maintain its state.

Update cread_line() to use this new function.

The only intended functional change is that an invalid escape sequence
does not add invalid/control characters into the input buffer, but instead
discards these.

The main issue the driver addresses is that a USB hub needs to be
powered before it can be discovered. This is often solved by using
"regulator-always-on".

This driver is inspired by the Linux v6.1 driver. It only enables (or
disables) the hub vdd (3v3) supply, so it can be enumerated.
Scanning of the device tree is done in a similar manner to the sandbox,
by the usb-uclass. DT part looks like:

&usbh_ehci {
	...
	#address-cells = <1>;
	#size-cells = <0>;
	hub@1 {
		compatible = "usb424,2514";
		reg = <1>;
		vdd-supply = <&v3v3>;
	};
};

When the bus gets probed, the driver is automatically probed/removed from
the bus tree, as an example on stm32:
STM32MP> usb start
starting USB...
STM32MP> dm tree
 Class     Index  Probed  Driver                Name

 usb_hub       1  [ + ]   usb_hub               |   |       `-- usb_hub
