UPSTREAM: clk: Add get/enable/disable/release for a bulk of clocks

This patch adds a "bulk" API to the clock API in order to get/enable/disable
/release a group of clocks associated with a device.

This bulk API will avoid adding a copy of the same code to manage
a group of clocks in drivers.

clk: implement clk_set_defaults()

Linux uses the properties 'assigned-clocks', 'assigned-clock-parents'
and 'assigned-clock-rates' to configure the clock subsystem for use
with various peripheral nodes.

This implements clk_set_defaults() and hooks it up with the general
device probibin in drivers/core/device.c: when a new device is probed,
clk_set_defaults() will be called for it and will process the
properties mentioned above.

Note that this functionality is designed to fail gracefully (i.e. if a
clock-driver does not implement set_parent(), we simply accept this
and ignore the error) as not to break existing board-support.

Cover-letter:
clk: support assigned-clock, assigned-clock-parents, assigned-clock-rates

For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC),
the parent-clock needs to be set via the DTS. This adds the required
plumbing and implements the GMAC case for the RK3399.

clk: refactor clk_get_by_index() into clk_get_by_indexed_prop()

clk: refactor clk_get_by_index() into clk_get_by_indexed_prop()

The logic in clk_get_by_index() may be useful for other properties
than 'clocks': e.g. 'assigned-clocks' and 'assigned-clock-parents'
follows the same model.

This commit refactors clk_get_by_index() by introducing an internal
function clk_get_by_indexed_prop() that allows to specify the name
of the property to process. The original clk_get_by_index() call
is simply directed through this helper function with the property
name fixed to "clocks".
