[U-Boot] [PATCH v2] gpio: stm32_gpio: Use clrsetbits_le32() at appropriate places

[Axel Lin <axel.lin@ingics.com>]

Use clrsetbits_le32() to replace clrbits_le32() + setbits_le32().

Signed-off-by: Axel Lin <axel.lin@ingics.com>

v2: Conver one more place (updating &gpio_regs->afr[dsc->pin >> 3] register)
    to use clrsetbits_le32().
