This commit adds cascade_counts_enable and external_input_phase_
clock_select items to counter ABI file.
(e.g. for Renesas MTU3 hardware used for phase counting).

Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>
Reviewed-by: William Breathitt Gray <william.gray@linaro.org>
 * Added Rb tag from William Breathitt Gray
 * Added available blocks for external_input_phase_clock_select_available
 * Removed the "This attribute" from the external_input_phase_clock_select
   description, and capitalize the word "counter" from description.
 * Removed the "This attribute" from the cascade_counts_enable description,
   and capitalize "counts" and "counter"
 * Moved these device-level configuration blocks to top of the file.
 * Replaced cascade_enable->cascade_counts_enable
 * Updated commit header and description
 * Added external_input_phase_clock_select_available entry for driver-
   specific enum attribute and created a new entry block for it.
 * Add a line stating cascade_counts_enable is a boolean attribute.
 * Added missing 'component_id' suffix.
 * Replaced long_word_access_ctrl_mode->cascade_enable
 * Updated Kernel version
 * No change
 * New patch
