pinctrl: imx: do not implicitly set pin regs to -1
Commit 3dac1918a491 ("pinctrl: imx: detect uninitialized pins") needs
the values in struct imx_pin_reg to be -1. This has been done in a
rather unorthodox way by setting the memory to 0xff using memset...
Use a proper for loop to initialize the whole array with -1.
