commit 2867b9746cef78745c594894aece6f8ef826e0b4 upstream.

Pointers should be cast with uintptr_t instead of integer. This fixes
warning when compile testing on ARM64:

drivers/clk/socfpga/clk-gate.c: In function ‘socfpga_clk_recalc_rate’:
drivers/clk/socfpga/clk-gate.c:102:7: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

Fixes: b7cec13f082f ("clk: socfpga: Look for the GPIO_DB_CLK by its offset")
