PHY Read support will be added for VSC 85xx Microsemi PHYs.

Why do i need this, when we have SIOCGMIIREG?

Microsemi PHY have different pages i.e. Std IEEE, Extended, Extended_2, Extended_3 and
GPIO pages.
When I want to use SIOCGMIIREG, I can read Std IEEE only with SIOCGMIIREG and not other 
pages.
phy_read_reg function is debug function where I can read entair PHY registers.
In this function, I set the page number and register address then read register value
as atomic operation.

Do you have any suggestions to implement this function in different ways?

Thanks,
Raju.
