Implement time management

[wipawel]

Add:

• timers support

• HPET
• APIC
• PIT

• jiffies support

• jiffies

• basic CPU frequency detection

• CPU frequency detection (e.g. via CPUID processor brand string parsing) to get a scale for tsc (Issue: [Feature] add CPUID processor brand string handling and parsing #80 )
• Ticks to nanoseconds scale based on CPU frequency
• CPU frequency calibration based on PIT
• CPU frequency calibration based on APIC Timer

• sleep functions with granularity:

• nano seconds
• micro seconds
• mili seconds
