    Revert "radio-tavarua: Configure search direction as passed by FM APP"

    As per V4L2 framework APP should pass the parameter as '1' to
    search in forward direction and '0' to search in downward
    direction. Reverting the change that was uploaded as it configured
    the search direction directly that it received it from the APP.
    APP should pass '1' for SEEK UP and '0' for SEEK DOWN . The driver
    should check for the direction before configuring. To the FM SOC,
    '0' means SEEK-UP and '1' means SEEK-DOWN. If APP passes '1' driver
    understands that user is requesting SEEK-UP operation and will
    configure the direction as '0'.

    This reverts commit 75b90b2359fe55e9e98906fbc088a32fe5537675

    interrupts to not to be enabled during next FM turn On
    operation and this results in GPIO not toggling for XFR operations.

    radio: radio-tavarua: Re-org code for workqueue

    When fm task is killed from task manager rpc failure is seen.
    <3>[   72.817162] pmapp_rpc_req_reply: rpc failed! len = -512
    <3>[   72.817173] fm_radio_shutdown: voting off failed with :(-512)
    RPC failure is because data to be sent from apps, was on behalf of the
    current process, but as the process is killed the current->pid given to
    rpc is a non-existing pid.
    To resolve the issue a valid pid is needed, which can be done by
    queueing a work in existing workqueue and wait for completion.

    radio: tavarua: Fix enum warnings

    The xfr_status variable is being read from an 8-bit unsigned register.
    Although the value definitions it is compared with are defined in an
    enum, these use bit arithmetic to define the cases (setting the high
    bit) which brings the constant values outside of the range of the
    enum.  This causes warnings on gcc 4.5.

    Fix this by keeping the value as an unsigned char.

    radio: tavura: Fix copy_from_user() warning

    The compiler is having a hard time determining that bytes_to_copy
    cannot be larger than XFR_REG_NUM. This causes a warning when
    strict user copy checks are enabled. Silence the warning by
    making bytes_to_copy unsigned, and use a more appropriate min
    function (min_t) on the bytes_left variable to help the compiler
    understand that the buffer will never overflow.
