linux-raspberrypi: Drop deprecated configs from android-driver.cfg

CONFIG_ASHMEM has been deprecated since 5.18 by:
    commit 721412ed3d819e767cac2b06646bf03aa158aaec
    Author: Christoph Hellwig <hch@lst.de>
    Date:   Tue Mar 15 13:34:57 2022 +0100

        staging: remove ashmem

        The mainline replacement for ashmem is memfd, so remove the legacy
        code from drivers/staging/

so has CONFIG_ANDROID since 6.1 by:
    commit 1045a06724f322ed61f1ffb994427c7bdbe64647
    Author: Christoph Hellwig <hch@lst.de>
    Date:   Wed Jun 29 17:01:02 2022 +0200

        remove CONFIG_ANDROID

        The ANDROID config symbol is only used to guard the binder config
        symbol and to inject completely random config changes.  Remove it
        as it is obviously a bad idea.

As now master has 6.1 or later, both should be dropped.
