Since commit 7b3415f581 ("MIPS: Loongson32: Remove
unused platform devices"), struct plat_ls1x_dma and plat_ls1x_nand
are unused. Then, dma.h and nand.h are useless.
Therefore, remove these useless header files.

Since commit 35508d2424 ("MIPS: loongson32: ls1c: Fix hang
during startup"), no one is calling ls1x_rtc_set_extclk().
Therefore, remove this obsolete function.
Since commit 9fb2309065 ("rtc: Remove the Loongson-1

commit 0060c87833 ("net: stmmac: implement support for passive mode
converters via dt") has changed the plat->interface field semantics from
containing the PHY-mode to specifying the MAC-PCS interface mode. Due to
that the loongson32 platform code will leave the phylink interface
uninitialized with the PHY-mode intended by the means of the actual
platform setup. The commit-author most likely has just missed the
arch-specific code to fix. Let's mend the Loongson32 platform code then by
assigning the PHY-mode to the phy_interface field of the STMMAC platform
data.

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().
remove_irq() has been replaced by free_irq() as well.
There were build error's during previous version, couple of which was
reported by kbuild test robot <lkp@intel.com> of which one was reported

Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
In preparation for making the clockevents core NTP correction aware,
all clockevent device drivers must set ->min_delta_ticks and
->max_delta_ticks rather than ->min_delta_ns and ->max_delta_ns: a
clockevent device's rate is going to change dynamically and thus, the
ratio of ns to ticks ceases to stay invariant.
Make the MIPS arch's clockevent drivers initialize these fields properly.
This patch alone doesn't introduce any change in functionality as the
clockevents core still looks exclusively at the (untouched) ->min_delta_ns
and ->max_delta_ns. As soon as this has changed, a followup patch will
purge the initialization of ->min_delta_ns and ->max_delta_ns from these
drivers.

Currently, code of Loongson-2/3 is under loongson directory and code of
Loongson-1 is under loongson1 directory. Besides, there are Kconfig
options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is
very ugly and confusing. Since Loongson-2/3 are both 64-bit general-
purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names
and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.
