[U-Boot] [PATCH 4/7] i2c: lpc32xx: use api to get hclk instead of fix value

[slemieux.tyco at gmail.com]

From: Sylvain Lemieux <slemieux at tycoint.com>

The HCLK is not constant and can take different value; use the api function to get the value of the HCLK for the I2C clock high and low computation.
