[U-Boot] [PATCH 1/2] usb: ehci-mx5: Remove unneeded write to cscmr1 register

From: Fabio Estevam <fabio.estevam at freescale.com>
Currently we have the following behavior in ehci_hcd_init()
- Read csmr1 register, clear bit 26 and then set bit 26.
However a little bit later we call set_usb_phy_clk() which clears bit 26, so
let's get rid of the unnecessary code.
