[PATCH] hw/usb: add configuration flags for emulated and passthru usb smartcard

[Jon Maloy]

We add two new configuration flags, USB_SMARTCARD_PASSTHRU and
USB_SMARTCARD_EMULATED in order to improve configurability
of these two functionalities.

Wouldn't this be better instead? (I don't think USB_SMARTCARD should
select PASSTHRU & EMULATED, but rather be selected for common shared
code)

config USB_SMARTCARD
    bool
    depends on USB

config USB_SMARTCARD_PASSTHRU
    bool
    default y
    select USB_SMARTCARD

config USB_SMARTCARD_EMULATED
    bool
    default y
    select USB_SMARTCARD

Yes, this is the way. (TM)

Also, you should add a "config LIBCACARD" (resp. "CONFIG_LIBCACARD=y")
symbol to Kconfig.host and the root meson.build, so that you can make these
symbols "depends on CACARD" and remove the "if cacard.found()" below.
