gd32l23x: patch HAL

Patch GD32L23X according to the requirements listed in the README.
This skip the i2c requirements, GD32L23X i2c have different implement.

   two step work. First move I2CCLK_MAX and I2CCLK_MIN marco from i2c source
   file to header file. Then split the I2CCLK_MIN for each supported transfer
