arm: vf610: fix delay when using global timer
The global timer used to divide the waiting cycles by two for no
reason, which lead to too short delays (e.g. when waiting for PHY).
This fixes an issue seen when bootdelay is 0 and the boot command
requires network:
FEC Waiting for PHY auto negotiation to complete......... TIMEOUT !
