[PATCH] net: phy: update fields of mii_ioctl_data for transferring C45 data.

[renjun wang <renjunw0@foxmail.com>]

The phy_id is used as u32 type in function mdio_phy_id_is_c45()
with the 30th bit for distinguishing C22 and C45. The reg_num is
also used as u32 type in function mdiobus_c45_read() or someplace
else. For more C45 information needed and data structure alignment
consideration, change these two fields to __u32 type which can make
user space program transferring clause 45 type information to kernel
directly.
