[PATCH 1/6 v3] mmc: meson-gx-mmc: Fix platform_get_irq's error checking

[PATCH 1/6 v3] mmc: meson-gx-mmc: Fix platform_get_irq's error checking

[Arvind Yadav]

The platform_get_irq() function returns negative if an error occurs.
zero or positive number on success. platform_get_irq() error checking
for zero is not correct.

changes in v2 :
              Add failure case '<= 0' instead of '< 0'. IRQ0 is not valid.
changes in v3 :
              return -EINVAL instead of irq.
