[PATCH] prism54 : Unused variable / extraneous udelay
In isl_38xx.c :
The variable "counter" is defined and incremented but never
used except if the driver is hand-compiled setting
VERBOSE > SHOW_ERROR_MESSAGES.
Move the definition and the increment to within the
#if VERBOSE .. block.
Remove extraneous udelay's.
These are not required when triggering the device.
