Revert "r8152: adjust the settings about MAC clock speed down for RTL8153"

[ Upstream commit 4b5dc1a94d ]

This reverts commit 134f98bcf1.

The r8153_mac_clk_spd() is used for RTL8153A only, because the register
table of RTL8153B is different from RTL8153A. However, this function would
be called when RTL8153B calls r8153_first_init() and r8153_enter_oob().
That causes RTL8153B becomes unstable when suspending and resuming. The
worst case may let the device stop working.

Besides, revert this commit to disable MAC clock speed down for RTL8153A.
It would avoid the known issue when enabling U1. The data of the first
control transfer may be wrong when exiting U1.
