[ Upstream commit 96f79935015cf3d7ca6fabf63cd13b8af45a7713 ]

GPIO_ALIVE and GPIO_CMGP blocks in Exynos850 SoC don't have EINT
capabilities (like EINT_SVC register), and there are no corresponding
interrupts wired to GIC. Instead those blocks have wake-up interrupts
for each pin. The ".eint_gpio_init" callbacks were specified by mistake
for these blocks, when porting pinctrl code from downstream kernel. That
leads to error messages like this:

    samsung-pinctrl 11850000.pinctrl: irq number not available

Remove ".eint_gpio_init" for pinctrl_alive and pinctrl_gpmc to fix this
error. This change doesn't affect proper interrupt handling for related
pins, as all those pins are handled in ".eint_wkup_init".

Fixes: cdd3d945dcec ("pinctrl: samsung: Add Exynos850 SoC specific data")
