The isp1760-rhcd.h header contains PTD constants and structures only

Revert "clk: ppc-corenet: Fix Section mismatch warning"
This reverts commit
da788acb28386aa896224e784954bb73c99ff26c.
That commit tried to fix the section mismatch warning by moving the
ppc_corenet_clk_driver struct to init section. This is definitely wrong
because the kernel would free the memories occupied by this struct
after boot while this driver is still registered in the driver core.
The kernel would panic when accessing this driver struct.

clk: rockchip: fix deadlock possibility in cpuclk
Lockdep reported a possible deadlock between the cpuclk lock and for example
the i2c driver.
CPU0 CPU1
---- ----
lock(clk_lock);
local_irq_disable();
lock(&(&i2c->lock)->rlock);
lock(clk_lock);
<Interrupt>
lock(&(&i2c->lock)->rlock);
*** DEADLOCK ***
The generic clock-types of the core ccf already use spin_lock_irqsave when
touching clock registers, so do the same for the cpuclk.
