i2c: observe scl_count in i2c_deblock_gpio_loop()
When compiling with -Wtype-limits we see this error:
drivers/i2c/i2c-uclass.c: In function ‘i2c_deblock_gpio_loop’:
drivers/i2c/i2c-uclass.c:517:21: error: comparison of
unsigned expression >= 0 is always true [-Werror=type-limits]
517 | while (scl_count-- >= 0) {
|
Don't loop forever.
