[PATCH] pwm: i.MX: eliminate build warning

[Lothar Waßmann]

compiling the i.MX pwm driver produces the following warning:
|drivers/pwm/pwm-imx.c: In function 'imx_pwm_probe':
|drivers/pwm/pwm-imx.c:281:7: warning: assignment discards qualifiers from pointer target type

Apply a 'const' attribute to the affected variable declaration.
