clk: ep93xx: Use int type to store negative error codes
Change the 'ret' variable in ep93xx_uart_clock_init() from unsigned int to int, as it needs to store either negative error codes or zero. Storing the negative error codes in unsigned type, doesn't cause an issue at runtime but can be confusing. Additionally, assigning negative error codes to unsigned type may trigger a GCC warning when the -Wsign-conversion flag is enabled. No effect on runtime.
