Subject: [PATCH] can: c_can_pci: limit compilation to archs with clock support

In commit:

  5b92da0 c_can_pci: generic module for C_CAN/D_CAN on PCI

the c_can_pci driver has been added. It uses clk_*() functions
unconditionally, resulting in a link error on archs without
clock support. This patch adds a "depends on HAVE_CLK" to the
Kconfig symbol.

An upcoming patch from Viresh Kumar adds a generic dummy
implementation. As soons as this patch has been merged, this
Kconfig symbol can be removed.
