r8152: Add support for the RTL8159 chip

Browse source

The RTL8159 re-uses the packet descriptor format introduced with the
RTL8157 and other hardware features of the RTL8157 (RTL_VER_16) such
as the SRAM access. The support therefore consists in expanding the
existing RTL8157 code for initialization and USB power management
to also be used for the RTL8159 (RTL_VER_17).

Most of the additional code is added in r8157_hw_phy_cfg() to configure
the RTL8159 PHY.

Add support for the USB device ID of Realtek RTL8159-based adapters,
for which the product ID is 0x815a. Detect the RTL8159 as RTL_VER_17
and set it up.
