[PATCH] spi: SPISG: Use devm_kcalloc() in aml_spisg_clk_init()

[Qianfeng Rong]

Replace calls of devm_kzalloc() with devm_kcalloc() in aml_spisg_clk_init()
for safer memory allocation with built-in overflow protection, and replace
sizeof(struct clk_div_table) with sizeof(*tbl) to shorten the line.
