Documentation: net: phy: remove description of function pointers

Remove the function pointers documentation which duplicates information
found in include/linux/phy.h. Maintaining documentation about two
different locations just does not work, but the code is less likely to
be outdated.

- Each driver consists of a number of function pointers:
-
-   soft_reset: perform a PHY software reset
-   config_init: configures PHY into a sane state after a reset.
-     For instance, a Davicom PHY requires descrambling disabled.
-   probe: Allocate phy->priv, optionally refuse to bind.
-   PHY may not have been reset or had fixups run yet.
-   suspend/resume: power management
-   config_aneg: Changes the speed/duplex/negotiation settings
-   aneg_done: Determines the auto-negotiation result
-   read_status: Reads the current speed/duplex/negotiation settings
-   ack_interrupt: Clear a pending interrupt
-   did_interrupt: Checks if the PHY generated an interrupt
-   config_intr: Enable or disable interrupts
-   remove: Does any driver take-down
-   ts_info: Queries about the HW timestamping status
-   match_phy_device: used for Clause 45 capable PHYs to match devices
-   in package and ensure they are compatible
-   hwtstamp: Set the PHY HW timestamping configuration
-   rxtstamp: Requests a receive timestamp at the PHY level for a 'skb'
-   txtsamp: Requests a transmit timestamp at the PHY level for a 'skb'
-   set_wol: Enable Wake-on-LAN at the PHY level
-   get_wol: Get the Wake-on-LAN status at the PHY level
-   link_change_notify: called to inform the core is about to change the
-   link state, can be used to work around bogus PHY between state changes
-   read_mmd_indirect: Read PHY MMD indirect register
-   write_mmd_indirect: Write PHY MMD indirect register
-   module_info: Get the size and type of an EEPROM contained in an plug-in
-   module
-   module_eeprom: Get EEPROM information of a plug-in module
-   get_sset_count: Get number of strings sets that get_strings will count
-   get_strings: Get strings from requested objects (statistics)
-   get_stats: Get the extended statistics from the PHY device

  Of these, only config_aneg and read_status are required to be
  assigned by the driver code.  The rest are optional.  Also, it is
