[PATCH] [ARM] imx1: add #define to configure frequency for the clk32

[Gwenhael Goavec-Merou]

From: gwenhael <gwenhael.goavec-merou at armadeus.com>

i.MX1 allows to use a 32kHz or a 32.768kHz quartz for the 32kHz clock source
(MC9328MXLRM p.177).
This patch adds the ability for the developer to change the default value for
the 32kHz clock source.
