clk: h8300: Use standard Linux I/O accessors
There doesn't seem to be any reason why we can't use the standard readb()/writeb() accessors here because ctrl_inb() and ctrl_outb() match the generic implementation of readb() and writeb() that the h8300 architecture uses. This allows us to test compile this driver on other architectures besides h8300. Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
