clk: fractional-divider: cast parent_rate to u64 before multiplying

On 32bit architectures, like ARM calculating the fractional rate will
do the multiplication before converting the value to u64 when it gets
assigned to ret, which can produce overflows.

The error in question happened with a parent_rate of 386MHz, m = 3000,
n = 60000, which resulted in a wrong rate value of 15812Hz.

Therefore cast parent_rate to u64 to make sure the multiplication
happens in a 64bit space and produces the correct 192MHz in the example.

net: ethernet: arc: Don't free Rockchip resources before disconnect from phy

Free resources before being disconnected from phy and calling core driver is
wrong and should not happen. It avoids a delay of 4-5s caused by the timeout of
phy_disconnect().
