The phy core provides a handy phy_speed_to_str() helper, so use that
instead of doing our own formatting of the different known link speeds.
To do this, increase PHY_LED_TRIGGER_SPEED_SUFFIX_SIZE to 11 so we can fit
'Unsupported' if necessary.

Commit 4567d686f5 ("phy: increase size of MII_BUS_ID_SIZE and
bus_id") increased the size of MII bus IDs, but forgot to update the
private definition in <linux/phy_led_triggers.h>.
This may cause:
1. Truncation of LED trigger names,
2. Duplicate LED trigger names,
3. Failures registering LED triggers,
4. Crashes due to bad error handling in the LED trigger failure path.
To fix this, and prevent the definitions going out of sync again in the
future, let the PHY LED trigger code use the existing MII_BUS_ID_SIZE
definition.
Example:
- Before I had triggers "ee700000.etherne:01:100Mbps" and
"ee700000.etherne:01:10Mbps",
- After the increase of MII_BUS_ID_SIZE, both became
"ee700000.ethernet-ffffffff:01:" => FAIL,
- Now, the triggers are "ee700000.ethernet-ffffffff:01:100Mbps" and
"ee700000.ethernet-ffffffff:01:10Mbps", which are unique again.

Create an option CONFIG_LED_TRIGGER_PHY (default n), which will create a
set of led triggers for each instantiated PHY device. There is one LED
trigger per link-speed, per-phy.
The triggers are registered during phy_attach and unregistered during
phy_detach.
This allows for a user to configure their system to allow a set of LEDs
not controlled by the phy to represent link state changes on the phy.
LEDS controlled by the phy are unaffected.
For example, we have a board where some of the leds in the
RJ45 socket are controlled by the phy, but others are not. Using the
triggers provided by this patch the leds not controlled by the phy can
be configured to show the current speed of the ethernet connection. The
leds controlled by the phy are unaffected.
