Subject: clk: scpi: fix return type of __scpi_dvfs_round_rate

From: Sudeep Holla <[email protected]>

[ Upstream commit 7374aec95636ca39409545eba4ef5ff3125c2346 ]

The frequencies above the maximum value of signed integer(i.e. 2^31 -1) will overflow with the current code.

This patch fixes the return type of __scpi_dvfs_round_rate from 'int' to 'unsigned long'.
